A couple of weeks ago, I bought a 'sensor kit' from Amazon for my son to use with his Raspberry Pi. It includes some input devices (e.g. button, moisture sensor) and output devices (e.g. LED) that can be plugged onto breadboard.
The setup instructions included something to do with CircuitPython. I had not heard of it before then: https://github.com/sunfounder/universal-maker-sensor-kit/blo...
