Line Follower Tutorial based on ATMega16 + L298 Motor Driver

Here the another Line Follower robot tutorial… The robot mechanical design not included, you may create the shape and the mechanical design of your line follower robot by your self. Just use motor gearbos which have high torque… :)

This line follower robot use the following module:

  • Proximity sensor: 8 pcs of phototransistors
  • Microcontroller: ATMega16
  • Motor driver: L298 module
  • Programming language: C

Sound Activation Schematic Diagram

Sound activation also knows as tone detector is one of sensing system that usually used for robot start up activation. When some frequency have received by microphone in this circuit, then the robot will start to move.

I’ve collected some schematic diagrams of sound activation as follow:
