Getting Moving with XOD – Robot Car Part 1

XOD Robot Part 1

XOD is a method of programming an Arduino using a graphical IDE instead of writing code. In XOD you use a collection of “nodes” connected by “links” to program your Arduino.

In this second installment on our series on XOD I’ll show you some ways of improving your XOD projects by using multiple patches, custom nodes and XOD libraries.

But the real fun is that in this article we’ll also start working on a practical project – a XOD robot! So let’s get started.

Build a Robot Car with Speed Sensors

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.
