Check out this great write-up from Ben Nuttall.
While preparing for a workshop last week, my colleague Marc and I started brainstorming ideas. One of the ideas I came up with was to use the mini joystick on a Sense HAT (a sensor board add-on for the Raspberry Pi) to remotely control a robot using GPIO Zero’s remote pins feature. I soon started writing the code for it on my laptop. Then I realised I could actually prototype the whole idea without touching a Raspberry Pi, using a combination of the Sense HAT’s desktop emulator developed by Dave Jones, and GPIO Zero’s mockpin interface (erm… also developed by Dave Jones).
