Step 3 Solder ATmega328 to PCB

follow the instructions on the following instructable (this one is explained better than I could possible try)

http://www.instructables.com/id/Perfboard-Hackduino-Arduino-compatible-circuit/

I will be referring to all pins on the ATmega328 as Arduino pins, I would recommend printing out the atmega328 to arduino pinout map from the above instructable on step 5 picture 2.

also solder a 10k resistor from digital 3 to ground, and another from digital 6 to ground
