# Micro:bit Radio Control of Crickit Robotics ## Overview https://youtu.be/6VlGi2315kg 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. ## Parts 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. ### Adafruit CRICKIT for micro:bit [Adafruit CRICKIT for micro:bit](https://www.adafruit.com/product/3928) Sometimes we wonder if robotics engineers ever watch movies.
