Line Follower

- an autonomous line following robot

Line followers are, well, robots that follow lines. Fairly common.

The objective of making this line follower to learn about sensors, making sensor circuits using pots and op-amps, and learning microcontroller programming. The sensor circuit was a eight-sensor array (all in a one-dimensional array). The eight sensors aid in more accurate sensing and more precise decision-making.

Atmel Atmega 32L was the microcontroller used for the embedded programming, and WinAVR was the IDE. IC7805 was used for the clipping and providing a constant 5V power supply, and the motor-driver used was IC L293D.

I later helped organize workshops for the same @ SRA, VJTI in 2009 and 2010.
