I've just purchased an UNO R3 a few months ago and I am already enjoying the knowledge I've gained by digging into the hardware. I've also started purchasing several Atmega328s with Arduino bootloader for DIY breadboarding. Once I figured out that I can't program two 328s using the UNO's 16U2, I loo…
