I recently purchased an Arduino Mega Android ADK (basically the Mega but with an extra USB port, as you probably know) because it was on clearance at RadioShack (only $24.99 - Not bad at all!). I do not have an Uno, and I was wondering if it is possible to upload a sketch to an ATMEGA328-PU chip using the Mega ADK? Would it be the same process as if I was doing so with an Uno? Thank you for any help ahead of time
Yes it should be possible.
Are you going to use the ArduinoISP sketch?
