CircuitPython
If you enjoy physical computing projects, the natural next step is to run Python on microcontrollers to control sensors, lights and sounds. For this there is CircuitPython. To give you a flavour of what can be done with CircuitPython (or its cousin MicroPython) take a look at these short YouTube videos of the Halloween 2023 project and Halloween 2024 project projects which my daughter and I worked on. You can read more about that adventure and see some other projects we've worked on at Coding Clubs by heading over to my GitHub project pages pico-interactive-halloween, pico-interactive and Circuit Python Toolkit for Interactive Projects (CPTKIP).
Don't be scared by any complex looking electronics. Getting started with CircuitPython or MicroPython is super easy and there are plenty of guides available. For some great places to start, take a look at the my CircuitPython links.
Most of the CircuitPython based projects I do at code club are fo special projects such as Christmas or Halloween so we do not do a huge number of them and there is no structured plan like with the other areas of the site.
