The BBC micro:bit continues to gain market share in the educational space. And why not, with an LED matrix display and a built-in Bluetooth LE radio, users can do some advanced projects.
In this guide, one micro:bit will be used as a radio control. Pushing the A and B buttons will transmit commands. A second micro:bit will be connected to an Adafruit Crickit robotics controller. The receiving micro:bit will translate the received radio commands into actions on the Crickit.
The Go bundle includes a battery pack, batteries, and a USB cable for a tiny bit more than the micro:bit alone. This is good for the transmitter.
The receiver is not battery powered, so the regular micro:bit pack is fine.
Adafruit Crickit for micro:bit provides robotics, sound, and light support.
We'll need a power supply for the Crickit and some interface items. You can choose, but for this tutorial we'll use a servo and an LED NeoPixel strip.
