I have the Dagu Mini Driver board which is based on the atmega8 and I uploaded the code here. It uploaded perfectly and I wired 4x AA pack to the battery terminals making sure to observe polarity.
I then attached two DC motors to the ML and MR pins just like it said in the picture. I turned the board on, making sure the switch was set to on also.
The red light lighted up and the blue light flickered for a second. The motors did not move. I tried different motors. To check if it was a corrupt bootloader I tried to upload the hello world blink sketch. That worked perfectly.
What in the world could be wrong? The code is supposed to make it turn in a rough square. I checked it over and over and it looks right. Any ideas?
