I hope you don't mind me saying this....but won't 2 IR sensors work better? Like both the sensors should be on the white part.....if the left sensor detects black meaning the bot has gone off course the left motor stops and the bot turns left until the sensor detects white again....and the same thing with the right motor........i think that would make the bot's movement smoother Just my opinion though

A mosfet is required because we cant connect the motors directly to the arduino This is because we need 12v power supply to operate the motor while arduino provides only 5v If we try supplying 12v through the arduino the arduino might malfunctionThis is where the mosfet comes in ...it connects the motor to arduino so that it can be controlled and also to a 12v battery for proper functioning of motor without passing the current from the 12v battery through the arduinoAlso thanks for viewing this instructable ...I hope it helped

Thanks

You welcome buddy

I am doing a project which involves using the speed of a motor so how do I find the acceleration of the motor using ADXL335
