The Pimoroni Pirate Radio Kit is a fun way to listen to your favourite streams. Although a sample playlist is provided, here's some links to get you started looking for some kid-friendly/educational streams..
Here's a couple of examples using the Kitronik ZIP Halo for the BBC micro:bit - that leverage the circular RGB LED configuration. Essentially, the Kitronik ZIP LEDs are programmed in the same way as Adafruit NeoPixels, as documented in the BBC micro:bit MicroPython documentation found online at: https://microbit-micropython.readthedocs.io/en/latest/neopixel.html
The BBC micro:bit supports the I²C bus protocol, for communicating with other devices, like sensors. In this post, I've used MicroPython to demonstrate, but the principles can easily be translated to lower and higher level languages.
The BBC micro:bit is a low-cost and accessible way to introduce kids with drag and drop coding experience to integrating with hardware, eg robots and sensors, and start to solve more practical problems. If you've never heard of the micro:bit, check out our quick and simple explanation of the BBC micro:bit. The BBC micro:bit PXT programming interface comes with a capable collection of blocks for coding with - these also allow access to send and receive data with accessories that can be attached to the micro:bit. This tutorial will show how to install extra blocks, in this case for the...
