There’s hardly a day that passes without an Arduino ... line follower. You’ve probably seen “bang-bang” line followers that just use a photocell to turn the robot one way or the other.

The dual-channel motor controller is a simple H-Bridge driver chip L293D. Brain of the line follower robot is one Atmega8 microcontroller. LFR-Mechanical Assembly First of all attach motors, clamps ...

Can your line following robot move faster than [Usain Bolt] who ... Inside the BeatBot an Arduino reads 9 infrared sensors for line detection at 100 samples a second. A digital servo controls ...

The motor driver circuit here is based on a simple 16-pin IC (L293D) which can drive two dc motors independently ... go into its input pins and the outputs are used to drive the robot motors.
