So we’ve got our robot moving in different directions and now we need it to move to the directions we want which is away from walls. We do this using Phototransistors which is sort of similar to a Light Dependent Resistor (a component that changes resistance due to lighting) except Phototransistors actually use infra-red and have two components, the emitter and detector. The emitter well emits the infra-red (which we can’t see) and the detector detects how much of that infra-red is coming back.

I’ve decided to make the next project that just about every person exploring electronics does… the making of a small robot. In my case, I’ll be using the Arduino to control the robot which will just be a robot that can avoid walls that  I might build more functionality in the future.

The first part of the project is to acquire the necessary parts such as motors, gears, wheels, infrared sensors, etc. Luckily for me, I actually had a robot that I was building up before; it’s the Cycbot from RealRobots (for anyone who might remember it). I got around to issue 6 or 7 and eventually gave up on it. I do however have the motors, gears, wheels and the motor controller, so it’s all actually working, it just goes forward for now.
