What are you building?

An automatically moving robot which follows the already drawn line on the floor with the help of IR Transmitting-Receiving LEDs. The accuracy of the movement of a line follower mostly depends on the motor movement and sensing system. Many algorithms are used to coordinate the line data read by the sensors to control the motors. But here a simple and most precise control is obtained by PID [Proportional Integral Derivative] algorithm.

 

Benefits:

The current set values can be viewed on the OLED display, and the same are automatically saved to EEPROM of the microcontroller, which makes testing the line follower with the PID algorithm simple and easier.

Parts list:

ATmega16 microcontroller, L293D motor driver & 2-DC motors, LM324 Op-Amp, IR Tx-Rx LEDs, 2.4cm OLED display etc.
