I'm now trying to integrate the code with some code i have had working to send a IR signal.
Sometimes the led stays high, I guess it could be due to the button press being to long? The orignal code used a serial command so only would run one, I tried adding a delay of 200 after signal is sent but didn't help.
Not sure if the new code is messing with the interrupts as it seems to disable then re-enable them?
Thanks
#include <avr/sleep.h>
//const byte LEDA = 13;
const byte LEDB = 12;
#define IRledPin 13
#define NumIRsignals 76
// This is the code I determined works for my Duraflame heater
int IRsignal[] = {
// ON, OFF (in 10's of microseconds)
