23+ Line Follower Robot Using 3 Ir Sensor PNG. I am working on building a line follower robot using atmega2560 and i want its movement to be more precise. But if you are planning to take that to the next level with some advanced movements let us start building our line following robot arduino by testing out the ir sensors and getting the readings out of them.
I have made an black. Else the robot is out of line so the robot keeps moving till one of the side sensors value changes then it turns to the remove the pic and test your sensors one by one using a voltmeter. This is just the beginning of line follower robot.
There are a lot of possible difficulties that can be set up for sir i m trying to use 8 ir sensor array.
This is a simple project of making a line follower using three ir sensors and a arduino board. We will use a simple ir based sensor, it is cheap and easy to build and use. A line follower is an array of infrared (ir) sensors. Black wire to gnd, red wire to sensor pin on the pic.
