Circuit Playground Express is the perfect introduction to electronics and programming — it has LED lights, buttons, sensors, audio, and it’s easy to program.

It also has built-in USB support. Built-in USB means you plug it in to program it, no special cable or adapter required. Just place your code into the circuit board, then take it on the go!

To program the board, we’ll use CircuitPython, a programming language designed to simplify experimenting and learning to program on low-cost microcontroller boards. It is based on Python.

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!
