Arduino led bar demo & sketch for 64x16 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);

//inputs for the select switches are: A1= Select, D9= Up and D7= Down

void switches()
/* 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…
