  • I tried building another one of these by loading the code above onto a ATMEGA 328 (uno optiboot) that I placed in my R3 uno board. I used the same display and parts I actually had lying around from other projects. Built this on a breadboard per the above schematic (all sparkfun parts too...). When power is applied, the buzzer rings continuously, but nothing else happens. Verified wiring, several times times and it is wired per the schematic. Placed the same ATMEGA328 back in board and ran some other sketches on it and no issues. I'm too new at programming to pursue this further, but I had the same exact problem.

No public wish lists :(
