Using an interrupt for my IR receiver

Hello Mike

Never sure exactly what 'bit banged' means!

Don't mind.... if you have time, then yes, that may help me understand the 'bit banging' part.

Hey all

Don't worry Mike. After literally messing around for hours with bit-bang SPI examples, I gave up and jumped over to I2C as a link between the Arduinos... far easier and works fine.

Still not really sure why having the USB programming lead connected to the PC has suddenly starting corrupting the existing SPI LedControl data however... odd
