It’s been a while since I last posted. So, uh, sorry about that. I’m going to make it up to y’all with this post. It’s in two parts: the video demonstrates the project in action, and the rest of this blog post details all the technical details. I’d recommend starting with the video to see the cool demo, and if you make it to the end, read the rest of the blog post.
For many years now, I’ve tutored at the National Computer Science School, which teaches computer science and programming to Australian high school kids. The school is divided into two parts: a web stream, which builds a website using Python, and an embedded stream, which (nowadays) uses MicroPython on the micro:bit.
Last year I tutored the web stream, and so it was only during the closing ceremony while watching videos demonstrating all the embedded students’ projects that I started wondering about the potential of the micro:bit, and whether I could build a mesh network so they could play music synchronized across a large area. So when work started getting quieter over the Christmas / New Year break, and this year’s NCSS started approaching, I decided to buy a couple of micro:bits and start hacking.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
