A 3-wheel vehicle that follows the path with the strongest source of light.
- An AVR micro-controller (I used ATmega328P) and a board to plug it AKA: Arduino UNO
- AA Batteries to power your board
- A Chasis for your vehicle
- Two DC motors in in micro servo body and a couple of wheels
- A dual motor DVR8835 driver to control your motors
- Three photo-resistors
- Three drinking straws to hold the photo-resistors 😎
- A switch, a breadboard and bunch of wires and resistors
And finally you're going to need a tool like Atmel Studio to compile and produce the .hex which you will load to the AVR with a program like XLoader.
