Here's an article I wrote over on my blog in which I use GPIO Zero and multi-threading to fade LEDs in and out using PWM from a Raspberry Pi Zero. This was in preparation for the Bett education conference (where it performed very well!) Read it here.
We hope to release some Raspberry Pi Zeros for sale on Monday!
Sonic Pi / Minecraft
The MagPi have published a tutorial that Sam Aaron, creator of Sonic Pi, wrote about live coding with his software. This tutorial has a twist, however, as it integrates with Minecraft: Pi Edition and allows you to build in the 3D world based on input from the musical environment of Sonic Pi. Well worth a look at if you want to captivate people with your creations. Read it here.
