Build a Robot Car with Speed Sensors

Build a Robot Car with Speed Sensors

I’m sure you have seen those inexpensive robot car chassis kits, the ones that come with two 6-volt motors. They are great fun and very useful and they even come with a couple of speed encoder disks (those little black circles full of holes). Problem is, no one tells you how to use them!

Let’s resolve that and build a robot car with speed sensors. Along the way we’ll learn how to use Interrupts, a valuable programming technique.

Getting Started Building Robots

Robots are the ultimate experimenters project. Nothing else lets you unleash your creativity more than designing a robot. And now with the availability of things like the Arduino and Raspberry Pi along with a wide assortment of mechanical parts and the ability to make your own with a 3D printer, robots have become a project that any dedicated experimenter can work on.

There are so many components and design considerations that must be taken into account when building a robot, This can often be overwhelming, especially when you’re creating your first automated device. This article should provide a firm foundation for getting started on your first (or next) robotics project.
