Ster en klok met Smart LEDs WS2812, Seeeduino xiaosamd21 cortex m0+ microcomputer, LDR control en DS3231 RTC nauwkeurige klok chip

De gebruikte onderdelen:  Meestal gebruik ik een AVR-type microcomputer zoals een Nano of een Mega maar bij een paar projecten met LEDS loop ik steeds vast op de beperking van geheugen. Daarom ben ik voor meer complexe projecten overgestapt op de Seeed studio XIAO SAMD21.  Lekker klein, snel en veel beschikbaar geheugen. Wel jammer dat ik alle code van de klok en dergelijke opnieuw moest maken, omdat de eerder gebruikte code alleen op AVR typen werkte.

De klok spreekt voor zich, de LDR gebruik ik voor automatisch  aanpassen van de lichtintensiteit, indien gewenst.  Alle belangrijke instellingen zijn via de USB-poort in te stellen.  De klok draait op UTC tijd en stelt zich zelf op het juiste moment in op de lokale zomer-of wintertijd.  Je moet dan eerst wel in de code de juiste regio selecteren.

Gemonteerd en heel compact:

En de montage van de 4 delen van de klok-LEDS in de 3d-geprinte ring waarin de delen met de LEDS worden gemonteerd:

En de werkende klok hier nog met een Arduino nano in plaats van een Seeeduino XIAO SAMD21 M0 en met een standaard klok voorbeeld programma:

Ronde klok WS2812 & Arduino nano

En meer gericht op effect dan op tijd:

Het coderen van een ster is iets complexer dan een ring omdat je meer figuren kan maken.  Een klok weergeven in een ster is misschien ook mogelijk, maar je moet er dan wel wat fantasie bij gebruiken.

GRA-AFCH NixieClockShield_NCS318_V1_94_TZ.ino met Time zone en zomer/wintertijd add-on met voorbeeld

Ik heb de timzone.lib plus arduino-additionele code toegevoegd aan de open-source code zoals GRA-AFCH die heeft gemaakt voor hun IN-18 nixie klok met Arduino Mega : NixieClockShield_NCS318_V1_94_TZ.

Hiermee synchroniseert de NIXIE klok via een aan te sluiten standaard GPS module met UTC (stond al in de code) en vervolgens met de juiste tijdzone, inclusief automatische verschuiving voor zomer- en wintertijd! (wat geheel nieuw is!)

Zie de werkende versie onder:

Het is nu gecodeerd voor West-Europa en een voorbeeld staat in de code voor een US tijdzone, andere kunnen worden afgeleid uit de voorbeelden die bij de nieuw toegevoegde timezone.lib zitten! #include <Timezone.h>//https://github.com/JChristensen/Timezone

Beschikbare tijdzones:

// Australia Eastern Time Zone (Sydney, Melbourne)
TimeChangeRule aEDT = {“AEDT”, First, Sun, Oct, 2, 660}; // UTC + 11 hours
TimeChangeRule aEST = {“AEST”, First, Sun, Apr, 3, 600}; // UTC + 10 hours
Timezone ausET(aEDT, aEST);

// Moscow Standard Time (MSK, does not observe DST)
TimeChangeRule msk = {“MSK”, Last, Sun, Mar, 1, 180};
Timezone tzMSK(msk);

// Central European Time (Frankfurt, Paris)
TimeChangeRule CEST = {“CEST”, Last, Sun, Mar, 2, 120}; // Central European Summer Time
TimeChangeRule CET = {“CET “, Last, Sun, Oct, 3, 60}; // Central European Standard Time
Timezone CE(CEST, CET);

// United Kingdom (London, Belfast)
TimeChangeRule BST = {“BST”, Last, Sun, Mar, 1, 60}; // British Summer Time
TimeChangeRule GMT = {“GMT”, Last, Sun, Oct, 2, 0}; // Standard Time
Timezone UK(BST, GMT);

// UTC
TimeChangeRule utcRule = {“UTC”, Last, Sun, Mar, 1, 0}; // UTC
Timezone UTC(utcRule);

// US Eastern Time Zone (New York, Detroit)
TimeChangeRule usEDT = {“EDT”, Second, Sun, Mar, 2, -240}; // Eastern Daylight Time = UTC – 4 hours
TimeChangeRule usEST = {“EST”, First, Sun, Nov, 2, -300}; // Eastern Standard Time = UTC – 5 hours
Timezone usET(usEDT, usEST);

// US Central Time Zone (Chicago, Houston)
TimeChangeRule usCDT = {“CDT”, Second, Sun, Mar, 2, -300};
TimeChangeRule usCST = {“CST”, First, Sun, Nov, 2, -360};
Timezone usCT(usCDT, usCST);

// US Mountain Time Zone (Denver, Salt Lake City)
TimeChangeRule usMDT = {“MDT”, Second, Sun, Mar, 2, -360};
TimeChangeRule usMST = {“MST”, First, Sun, Nov, 2, -420};
Timezone usMT(usMDT, usMST);

// Arizona is US Mountain Time Zone but does not use DST
Timezone usAZ(usMST);

// US Pacific Time Zone (Las Vegas, Los Angeles)
TimeChangeRule usPDT = {“PDT”, Second, Sun, Mar, 2, -420};
TimeChangeRule usPST = {“PST”, First, Sun, Nov, 2, -480};
Timezone usPT(usPDT, usPST);

De benodigde arduino libraries staan op de GRA-AFCH Github pagina’s hier:

of download alleen de Libraries

Het werkt echt goed, zie het gezipte bestand hieronder of de arduino code verderop:

//// This can and may be used in any CLOCK program, with possibly specific minor alteration, due to different libraries and do on ////
//// All of my add-ons are specified in the code! Cheers, Jantec.nl, NL ////
//// The approach here is to automatically change the EEPROM hours setting according to the SUMMER/WINTER timescheme ////
//// meaning: Put in the register: a) the time zone (=normal winter time) versus UTC and b) at the switching times the summer ‘+1’ change versus ‘normal’wintertime ///
//// If the user changes the hours setting, this will be overruled at every programmed time change related to summer/ winter time

Kerstster deur/raamhanger Arduino nano en WS2812 LEDS en LDR

Geprint op de Voron2.4-300 met wit PETG filament.

De ster bestaat uit 5 gelijke delen. Je moet de 5 delen printen, de LED’s er doorheen voeren en daarna de draden er ergens uit laten komen.  De punten kun je na het monteren en testen aan elkaar lijmen met hotglue of superglue.

De 3 draden van de WS2812 LED string soldeer je aan de Arduino Nano (5V aan 5V, Gnd aan Gnd en de Data IN van de LED string soldeer je aan D3 of D5 van de Arduino Nano.  That’s it!   Daarna kun je de Arduino aan je PC koppelen met een data USB kabel en kun je de code downloaden van mijn website.

undefined

IK houd het meestal gemakkelijk en gebruik een telefoonlader met een USB kabel, die past in de Arduino nano.  Dan soldeer je de 3 draden van je WS2812 leds aan VIN (+), GND (-) en D5 (data).  Optioneel kun je een LDR (lichtgevoelige weerstand) aansluiten op A0 en Gnd.

In mijn latere ontwerpen heb ik dus een LDR toegevoegd tussen A0 en Gnd.  Met een stukje extra code is de intensiteit van de ster nu automatisch afgestemd op het omgevingslicht.  Daarnaast heb ik een aantal extra lichteffecten gemaakt.

 

Als je de Arduino IDE nog niet hebt, download dan de app van de Microsoft website (Arduino IDE).

Zorg dat je mijn Arduino code download en open dit met de Arduino IDE APP> Waarschijnlijk moet de APP de arduino INO file nog herplaatsen in een nieuwe directory maar dat hoort vanzelf te gaan. Zo niet, doe dat dan zelf even.

Selecteer in de Arduino IDE de juiste microprocessor (Arduino Nano)..  Vervolgens de juiste versie processor (groot of klein geheugen) en de oude of nieuwe bootloader.  Deze keuzes zijn afhankelijk van het soort Nano dat je hebt gekocht of nog had liggen.  Daarna kies je de juiste poort (USB) voor je Nano.

Om te testen of je verbinding hebt tussen IDE en Nano , kun je opvragen of de Arduino IDE je Nano kan lezen.  Pas hierna kun je de Nano gaan laden met het gecomplieerde programma.

Succes!

De Arduino code zonder LDR staat HIER.

De arduino code MET LDR staat HIER:

De STL file voor de 76cm ster staat HIER.  Deze moet je 5x printen en in elkaar lijmen.  De LEDS kun je binnen door elk segment voeren.  Dat is een beetje puzzelen maar echt mogelijk.  Zie het voorbeeld:

Ronde klok WS2812 & Arduino nano

ABOVE: Circular clock, completed project, reading 05h:41m and crossing to 05h:42m.  Red=hours, Green=minutes

Above: Clock without case, with open components.

READ THIS ARTICLE IN ENGLISH

In de bovenstaande video zie je alle benodigde onderdelen voor de electronica.  Een arduino Nano, een tijdmodule LS3231 met batterij back-up en een 4-delige ring met elk 15 stuks WS2812 LED’s die zorgen voor een 160mm 60 LED units klok.  Je kunt hem bouwen als een open gebouwde unit zoals hierboven afgebeeld met draad of in een 3d printbare slanke behuizing die ik heb ontwikkeld.  Zie de foto’s hieronder.

Voor het bouwen van deze mooie nauwkeurige klok, kun je mijn ontwerp files voor de behuizing gebruiken op elke 3d printer met een horizontale bed maat van minimaal 165x165mm.

Download de beide print STL’s OF van de Prusa gedeelde site waar ik deze ontwerpen heb geupload (zoek op de prusa site naar ws2812 circulaire arduino klok).

OF haal het STL bestand voor de VOORKANT van de klok van mijn website HIER

EN haal het STL bestand voor de ACHTERKANT van de klok van mijn website HIER

Eén STL is voor de achterkant en bevat de Nano box, de andere is voor de voorkant van de klok.  Positioneer de achterste STL 180 graden (dus omhoog gaat omlaag) in uw slicer, zodat zowel de doos als de LED-behuizing op Z-0 niveau zijn, d.w.z. naar beneden gericht op hetzelfde horizontale niveau.   De voorkant kan het best geprint worden met de platte kant naar beneden.  ABS is niet aan te raden omdat het minder stijf is, maar zal waarschijnlijk ook werken.  Voor mij werkt PETG of PLA het beste.

Gebruik wit filament voor het voorste deel, de achterkant kan elke kleur zijn die je wilt.

In de cirkel worden de 4 WS2812 LED segmenten in 1 volledige cirkel van ongeveer 160mm geplaatst.

Als je de elektronica aan de achterkant hebt aangesloten, schuift de voorkant er zo overheen. Geen lijm nodig.  Maar de LED ring kan best op 4 plaatsen met een druppel hotglue aan de basis van de achterste behuizing gelijmd worden.  Dit kun je het beste doen als je zeker weet dat alles goed werkt.

De LED onderdelen zijn verkrijgbaar op o.a. banggood , aliexpress en zo, zoek naar 60LED circle WS2812 die de 160 mm buitendiameter heeft.

Elke LED vertegenwoordigt een punt voor seconden, minuten of als uur indicator.

De kleuren bepalen de functie.  Blauw wordt ook gebruikt als kwartier indicator met minder intensiteit, om een gevoel van positionering te hebben voor de andere LEDS als het donker is.

Kijk naar de video hierboven van het ‘open’ demonstratiemodel om te begrijpen hoe het werkt.

Hieronder vindt je de Arduino code voor de gebruikte Nano3, as-is. het werkt voor mij, en in de code vindt u ook alle benodigde elektrische aansluitingen en de specificaties van de gebruikte Time module.

Haal de Arduino code HIER

Wanneer aangesloten op je PC, kun je de Arduino programmeren en via de seriële interface kun je naderhand speciale instellingen van de klok wijzigen, zoals helderheid, speciale kwartierverlichtingsindicatoren, enzovoort. het staat allemaal in de code hieronder.

De aansturing kan via een seriële interface met de usb ingang van de Arduino, via een terminalprogramma zoals YAT of met de interface van het Arduino IDE programma.

De commando’s zijn:

f; fader UIT
F; fader AAN
m (getal); dim de 4 blauwe marker LED’s met waarde (getal)
S; synchroniseren met RTC tijd
s; synchroniseren met systeemtijd (computer)
t (tijd); systeemtijd veranderen in:
b; helderheid van alle niet-marker LED’s

Doneer a.j.b. $1 aan mijn paypal account als je (delen van) mijn ontwikkelde materialen gebruikt, zodat ik kan doorgaan met het delen van leuke dingen voor jou om te downloaden

Ik hoop dat alles goed gaat lukken!

Succes,

Jan

De Arduino code, te gebruiken voor het programmeren van de Arduino Nano3 is beschikbaar onderaan dit bericht als platte tekst om te importeren in een leeg arduino bestand (met kopiëren en plakken).

Zorg ervoor dat je alleen de bibliotheken en tijdmodule gebruikt die in de code zijn aangegeven!  De gebruikte tijdmodule is van de betere generatie die de tijd zeer goed vasthoudt, ook in stand-by.

Gebruik voor het verbinden van de draden tussen de neopixel segmenten, de arduino en de tijdmodule een temperatuurgeregelde soldeerbout.  Gebruik een ventilator als je aan het solderen bent en adem geen giftige gassen in tijdens het solderen.

De Arduino code is hieronder weergegeven, te importeren in Arduino IDE in een .ino bestand.  Met de Arduino IDE moet je vervolgens de code compileren om de Arduino Nano geflasht te krijgen met het programma.

OCTOWS2811, Teensy 1.4 & JINX 64×32 LED display

Het gebruik van een octoWS2811 is de eenvoudigste manier om een LED display te maken zoals hierboven getoond.

Om dit goed te laten werken moet je eerst een Teensy module flashen met de juiste firmware. OctoWS2811Demo

Daarna sluit je de teensy aan op de OCTOWS2811 connector-insteekmodule.

In de2  RJ45 bussen van de OCTOWS2811 module steek je 2 LAN kabels en het andere uiteinde sluit je aan op de ingang van de WS2812 LED modules.

Het maximum aantal aansluitingen op de LED matrices of van de DIY strings van WS2812’s is 2×4=8 (Octo).

Download en start vervolgens JINX.

Sluit de Teensy met de USB poort aan op je PC/Laptop.

Sluit je LED matrixen aan op een krachtige 5V PSU.

Controleer je bedrading.

Definieer je WS2812 setup in JINX (grootte X*Y, type richting, zigzag of anders, etcetera) zodat de output al correct geformatteerd zal zijn voor je setup.

Start elke uitvoer en test het.  Indien niet OK, pas dan de setup aan van de LED matrix/buizen.

 

Ronde klok WS2812 & Arduino nano

READ THIS ARTICLE IN ENGLISH

In de bovenstaande video zie je alle benodigde onderdelen voor de electronica.  Een arduino Nano, een tijdmodule LS3231 met batterij back-up en een 4-delige ring met elk 15 stuks WS2812 LED’s die zorgen voor een 160mm 60 LED units klok.  Je kunt hem bouwen als een open gebouwde unit zoals hierboven afgebeeld met draad of in een 3d printbare slanke behuizing die ik heb ontwikkeld.  Zie de foto’s hieronder.

Voor het bouwen van deze mooie nauwkeurige klok, kun je mijn ontwerp files voor de behuizing gebruiken op elke 3d printer die een horizontale bed size heeft van minimaal 165x165mm.

Pak de beide print STL’s . HIER. van de Prusa gedeelde site waar ik deze ontwerpen heb geupload. (Als de link breekt, zoek op de prusa site naar ws2812 circulaire arduino klok).

OF haal het STL bestand voor de VOORKANT van de klok van mijn website HIER

EN haal het STL bestand voor de achterkant van de klok van mijn website HIER

Eén STL is voor de achterkant en bevat de Nano box, de andere is voor de voorkant van de klok.  Positioneer de achterste STL 180 graden (dus omhoog gaat omlaag) in uw slicer, zodat zowel de doos als de LED-behuizing op Z-0 niveau zijn, d.w.z. naar beneden gericht op hetzelfde horizontale niveau.   De voorkant kan het best geprint worden met de platte kant naar beneden.  ABS is niet aan te raden omdat het minder stijf is, maar zal waarschijnlijk ook werken.  Voor mij werkt PETG of PLA het beste.

Gebruik wit filament voor het voorste deel, de achterkant kan elke kleur zijn die je wilt.

In de cirkel worden de 4 WS2812 LED segmenten in 1 volledige cirkel van ongeveer 160mm geplaatst.

Als je de elektronica aan de achterkant hebt aangesloten, schuift de voorkant er zo overheen. Geen lijm nodig.  Maar de LED ring kan best op 4 plaatsen met een druppel hotglue aan de basis van de achterste behuizing gelijmd worden.  Dit kun je het beste doen als je zeker weet dat alles goed werkt.

De LED onderdelen zijn verkrijgbaar op o.a. banggood , aliexpress en zo, zoek naar 60LED circle WS2812 die de 160 mm buitendiameter heeft.

Elke LED vertegenwoordigt een punt voor seconden, minuten of als uur indicator.

De kleuren detemine de functie.  Blauw wordt ook gebruikt als kwartier indicator met minder intensiteit, om een gevoel van positionering te hebben voor de andere LEDS als het donker is.

Kijk naar de video hierboven van het ‘open’ demonstratiemodel om te begrijpen hoe het werkt.

Hieronder vindt u de Arduino code voor de gebruikte Nano3, as-is. het werkt voor mij, en in de code vindt u ook alle benodigde elektrische aansluitingen en de specificaties van de gebruikte Time module.

Wanneer aangesloten op je PC, kun je de Arduino programmeren en via de seriële interface kun je naderhand speciale instellingen van de klok wijzigen, zoals helderheid, speciale kwartierverlichtingsindicatoren, enzovoort. het staat allemaal in de code hieronder.

De aansturing kan via een seriële interface met de usb ingang van de Arduino, via een terminalprogramma zoals YAT of met de interface van het Arduino IDE programma.

De commando’s zijn:

f; fader UIT
F; fader AAN
m (getal); dim de 4 blauwe marker LED’s met waarde (getal)
S; synchroniseren met RTC tijd
s; synchroniseren met systeemtijd (computer)
t (tijd); systeemtijd veranderen in:
b; helderheid van alle niet-marker LED’s

Doneer a.j.b. $1 aan mijn paypal account als je (delen van) mijn ontwikkelde materialen gebruikt, zodat ik kan doorgaan met het delen van leuke dingen voor jou om te downloaden

Ik hoop dat alles goed gaat lukken!

Succes,

Jan

De Arduino code, te gebruiken voor het programmeren van de Arduino Nano3 is beschikbaar onderaan dit bericht als platte tekst om te importeren in een leeg arduino bestand (met kopiëren en plakken).

Zorg ervoor dat je alleen de bibliotheken en tijdmodule gebruikt die in de code zijn aangegeven!  De gebruikte tijdmodule is van de betere generatie die de tijd zeer goed vasthoudt, ook in stand-by.

Gebruik voor het verbinden van de draden tussen de neopixel segmenten, de arduino en de tijdmodule een temperatuurgeregelde soldeerbout.  Gebruik een ventilator als je aan het solderen bent en adem geen giftige gassen in tijdens het solderen.

De Arduino code is hieronder weergegeven, te importeren in Arduino IDE in een .ino bestand.  Met de Arduino IDE moet je vervolgens de code compileren om de Arduino Nano geflasht te krijgen met het programma.

Arduino led bar demo & programma voor 64×16 Canton electronics LED matrix

Module No.:  TB275

//#include <AT24Cxx.h>//no lib needed since we will only use basic functions in 1 page at first

// Author: Phil Kaziewicz 19th July 2014,
// Jan Griffioen did quite some ADDITIONS july-nov 2014 such as RTC, temp, humidity, barmetric pressure, stringtext in time, funny roll-ups etc and voidstructuring
// 64×16 LED display matrix test code
// based upon original code from canton-electonics
// Arduino 1.0.6 NANO V4.0 (with the 2008 Windows drivers; these work with W8.1;

// add buttons or wire bridges for intensity (if possible), speed, language, time up and time down (both last buttons work more agressively when kept pushing…)
// will also try to adapt rotary switches for settings…
// D9& D?? are free for this
// A1 and A3, A6 and higher are free for this, preferrably with a resistor network like on the LCD shields, that should only consume 1 A-pin…
// Add a device for proximity and connect to a ‘button’ input for something like speed or intensity// crash,…
// The development is done with a Nano, after all is OK the pro mini will be glued to the rear of the board and one time programmed via a USB to TTL converter.
// Re-programming only on request!

#include <dht.h>

// Example testing sketch for various DHT humidity/temperature sensors
// Written by ladyada, public domain

#define DHTPIN 16 // what pin we’re connected to; A2=D16

// Uncomment whatever type you’re using!
#define DHTTYPE DHT11 // DHT 11
//#define DHTTYPE DHT22 // DHT 22 (AM2302)
//#define DHTTYPE DHT21 // DHT 21 (AM2301)

// Connect pin 1 (on the left) of the sensor to +5V
// NOTE: If using a board with 3.3V logic like an Arduino Due connect pin 1
// to 3.3V instead of 5V! with shield 5V is OK
// Connect pin 2 of the sensor to whatever your DHTPIN is
// Connect pin 4 (on the right) of the sensor to GROUND
// Connect a 10K resistor from pin 2 (data) to pin 1 (power) of the sensor

// Initialize DHT sensor for normal 16mhz Arduino
DHT dht(DHTPIN, DHTTYPE, 10);
// NOTE: For working with a faster chip, like an Arduino Due or Teensy, you
// might need to increase the threshold for cycle counts considered a 1 or 0.
// You can do this by passing a 3rd parameter for this threshold. It’s a bit
// of fiddling to find the right value, but in general the faster the CPU the
// higher the value. The default for a 16mhz AVR is a value of 6. For an
// Arduino Due that runs at 84mhz a value of 30 works.
// Example to initialize DHT sensor for Arduino Due:
//DHT dht(DHTPIN, DHTTYPE, 30);

/* the intent here is to use a couple of hardware switches to set all parameters of the system, so you don’t need to update it with the PC.
The systems becomes independent in this way and possibly it can be a sellable item then.

There will be 3 switches: Select , Up and Down. If there is enough room, I will connect them all three to available inputs:
A1= Select,
D9= Up and
D7= Down

The structure is for Select to halt the running programs through the interrupt that is built in the wait void!
Once you are in the switches void the structure is to g through setup with Up and Down, choose the appropriate setting ans Select is, after which you
can again select a new option if available and so on.

I will try to make a function that allows you to press Up and Down at the same time to return immediately or to use is as a reset possibility…

Up and down could also be used as up/down time/date/others by pressing where long press fastens the speed of change…
