Before I started building the $50 robot I thought it would be good to have some kind of circuit diagram or at least a check list of what needs to connect to what. Mainly so I could check my soldering, volatages etc etc. So thought I would post the attached PDF document (in a ZIP file) that allows you to turn on/off layers on the board to see what's what. Old news to most - but 'may' be good news to some.
@ DMCLIFTON : exectute le schematics from Webbot exactly. Although similar to Admin's there are differences (yeah...the 5v regulator is one). I redone mine and all is working. Go exactly as webbot says!
I was considering doing the $50 robot on a breadboard and saw this and decided to change my mind, this schematic makes making the controller look a lot easier i just have one question: the wiring looks a bit different from admins to me, not sure if that's the case just want to make sure before i start. thanks.
I followed your schematic but on the last part and I ran into a problem. When I plug the power, the LED not turn on. Anyone know why this would be?Than I use USBasp to connect and programing the micro, but my computer can't recognise the driver, can anyone help me with this problem?Thanks...
Cant you guys just post the complete eagle project?
i followed the schematic but when i try to input a hex file for the photovore through AVR studio 4...i get "entering programming mode...FAILED!" im using an ATmega8 with AVR ISP2 Programmer
