A short Saturday side project
I made this for fun on a Saturday morning. The parts I used were all from my recycle box, except for the digital line tracker sensor boards. If you want to make a similar project, it is quite easy and you can use almost any basic robot base.
The code is simple too – Just stop the right motor when the right sensor senses the line, and the left motor when the left sensor senses the line. I made it stop when both sensors see black.
