I am attempting to program a Rainbowuino v2.0 with an Arduino Mega.
I have connected up the tx-tx and rx-rx and other wires as specified, but I am having no luck getting it to work.
The error I get from the Arduino IDE is as follows;
avrdude: Expected signature for ATMEGA328P is 1E 95 0F
Double check chip, or use -F to override this check.
Any ideas? This is driving me insane.
