$50 Robot Schematic
« on: November 08, 2007, 12:37:22 PM »
I have just got all the components to start the $50 robot schematic. I am going to use a breadboard, and I was wondering if anyone has drawn up a line schematic for the bot. The colored dot schematic is nice, but it left me with a few questions.
-Thanks,
Buk

OK, so i got off my lazy butt and did it myself. It is a pretty crummy job, i did it in paint. If anyone would take the time to look at it and tell me if i did anything wrong, please give me input!

Thanks,
Buk

I didnt check the pin numbers, but the rest looks correct.

After reading some of the datasheet for the mega 8 and a couple of related posts, it seems like pin one should be set at a normally high state. Should i tie it in to the requlated voltage to keep my chip from resetting?

Sorry to interrupt but:

Only thing though is that it doesnt come with an ATMega8 symbol for the MCU library. I have to make my own XP
