Why Learn CircuitPython?
CircuitPython is a programming language designed to simplify experimenting and learning to program on hardware devices. It makes getting started with low-cost microcontroller boards easier than ever before.
It adds hardware support for Python, so if you already have Python knowledge, you can easily apply that to using CircuitPython. If you have no previous experience, it’s really simple to get started!
Take-Away Skills
This course will start with learning how to light up the colors on the Circuit Playground Express using its buttons and NeoPixel LEDs before digging deeper into the more advanced features such as audio output and touchpads. You will use the Circuit Playground Express to build projects such as:
- Bike Light
- Plant Care
- 808 Drum Machine
