We are using microcontroller Atmega8l as our robots brain.
Programming is done in WinAvr software. To burn this program we converted it into .hex file and using Linux Operating System and parallel port we burn it. We need only one parallel port cable, three resistors and two wires for this.
Our requiremet is:
1. Line following robot
2. mechanism for robot hand up/down
3. mechanism to beat the three drums
