As I have reflected on various physical computing activities we tried with our kids, I started reviewing a novel microcontroller from our friends at the BBC, the micro:bit. In addition to the BBC bringing us awesome stories like Dr. Who, this organization has invested their resources to help students connect to creative computing tools for young makers. The BBC micro:bit continues this cool tradition by offering inexpensive microcontrollers to empower students to build robots, explore wearable computing, and invent new stuff. The BBC micro:bit device has an amazing set of features: Bluetooth or radio communication, a compass sensor, shake sensor, a couple of push buttons, a grid of LED lights, compact battery pack and a good number of inputs and outputs. The input/outputs enable the student to drive servos, drive speakers or connect to other electronics. I love this platform since novice makers can program the microcontrollers with block programming. Advanced students will enjoy the ability to program the microcontrollers with languages like JavaScript and Python. That’s a lot of capability for a low-cost microcontroller under $30. I believe the BBC micro:bit can be a fine alternative to an Arduino for beginners.
The micro:bit community has done a great job of putting together helpful tutorials and lessons for a wide range of students.
