IR Record and Playback module

[blacey]

@BartE, awesome! Your sketch should work perfectly with the IR Blaster. Perhaps you would be a good beta tester - where are you located?

[BartE]

@blacey this i've though about that too. (the IR-led i've tested with has a poor broadcast range)
I'm living in the Netherlands

Adding some Vera screenshots

[pete1450]

@BartE As I'm already using a sensor that I just control with light switch buttons in vera, I'd like to not have to add a IR receiver to the current board. Does this have the ability to let me just add the hex codes I already have?

Either way this is awesome.

[BartE]

@pete1450 i've added your feature request in version 1.1 of my plug in sketch You can add up to 240 RC HEX commands, from line 111, if you use an Arduino with enough memory. 40 will do with an Arduino UNO

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 *******************************
 *
 * REVISION HISTORY
 * Version 1.0 - Changed for MySensors useage by Bart Eversdijk
 * Version 1.1 - Added option to record manual presets up to 240
 * 
 * DESCRIPTION
 *
 * IRrecord: record and play back IR signals as a minimal 
 * An IR detector/demodulator must be connected to the input RECV_PIN.
 * An IR LED must be connected to the output PWM pin 3.
 * A button must be connected to the input BUTTON_PIN; this is the
 * send button.
 * A visible LED can be connected to STATUS_PIN to provide status.
 *
 * The logic is:
 * If the button is pressed, send the IR code.
 * If an IR code is received, record it.
