Build Your Own Microcontroller Based PID Control Line Follower Robot (LFR)

One of the interesting parts in building the Line Follower Robot is; you could start it with a very simple version by using just two transistors with the LED and LDR for sensor and enhance it to the programmable version that use microcontroller as the brain for controlling the robot. The reason of using the Microcontroller for the Line Follower Robot is we need to make more robust, reliable and flexible robot which you could not have it from the discrete electronics component robot without changing most of the electronic circuit design.

[achanta1000]

is it same procedure for ATMEGA8?

@achanta1000, the code will be slightly changed.

My proportional control LFR is much faster. Your PID gains need more tuning because there are visible oscillation and overshoot.

nice tutorial, thank you man, nice music too (the autumn leaves) one of my favourites

This is a brilliant Robot, so fast and the way it refinds the line is just amazing.
