People have done some cool stuff controlling Raspberry Pi robots with Nintendo Wiimotes. Now I don’t have any robot bits, but I do have an old Wii sitting unloved upstairs, so I found the remote, put batteries in it and started to think about what I could do.
I can’t drive a robot, but I can drive a turtle – a virtual Python graphics turtle. So I made a paint program that is controlled using a Wiimote. I based the code on the excellent example on the Raspberry Pi Spy web site – Python code below.
You are in effect driving the turtle, and as such I think this is possibly quite useful for teaching how Python turtles work as you have to think from the Turtle’s point of view: if it’s facing down you need to turn right to go left. I’ve added some code to get readings from the accelerometer to turn left & right as well as using the left & right arrow buttons.
