Take your micro:bit to the next level with this ElecFreaks micro:bit Tinker Kit. This ElecFreaks Tinker Kit is the ultimate micro:bit add-on package for the tinkerer or maker in your life! They'll spend hours working through modules, like making a moisture sensor, a plant soil monitor, and more. But to get started with this ElecFreaks Tinker Kit, they'll need a micro:bit Bundle first.

With this kit, you'll discover fun & creative ways to learn new coding and electronic skills. Inside, you'll find a micro:bit adapter for easy connection to your micro:bit device, and each of the included accessories come on specially designed boards. No breadboard required!

Discover how to use a variety of electronic components like LEDs, different sensors, a potentiometer, a buzzer, and a 5-button gaming keypad. The kit's moisture sensor, mini OLED display, and micro:bit breakout board bring even more fun and sophistication to your learning experience. With this ElecFreaks Tinker Kit, you can use your limitless creativity to make a 5-key music machine, a motion-sensing light, a soil moisture sensor and display that tells you when your plants are thirsty, and more hands-on DIY projects.

We provide instructions that show you how to code the device using block coding, like MakeCode or Scratch. This ElecFreaks micro:bit Tinker perfect for beginners, but more advanced coders can replicate the same programs using a more complex language if desired (ex. JavaScript, Python, etc.). This kit requires two AAA batteries, which are included in our micro:bit Bundle. If you did not get the HST micro:bit bundle, you'll need to supply your own batteries.
