how to make line following robot

[goatfish]

does anyone have any knowledge to share with me on how to make a line following from scratch,including how to program it and things like that,i shoulod be able to come up with a design for the robot,i just need to know what electronics i would need and how to program it.if anyone has anything it would be greatly appreciated

well u dont need the microcontroller for applications like the line follower look in the $40 robot tutorial, ull get ur answer

yea but i want to make it from scratch,getting all the parts cheap(but i know work  ) and programming from scratch,just i need someone to tell me what code i need it in,also i currently only have the ATmega 8 chip

if u look in the programming tutorials ull know what should be the algorithm , once u know the algorithm , it depends upon u to write the best suiting code accoding to the algorithm

admin made a tutorial using the $50 robot toi make a line follower using the atmega 8

trust me the admin's edge detection algo will be a little tough for u , just concentrate on keeping it simple "KISS"
