This line following Add-on board is a great addition to your robot project.
Designed to fit the Kitronik laser-cut robot kit it is ideal for those wanting to get into soldering and assembling electronics themselves.
It uses two LDRs to detect the left and right edges of a line. A logic signal indicating the state of each LDR can then be connected to the motor controller board allowing a simple line following control routine to run.
