I purchased this module as part of another microcontroller kit, its an interesting little module as it has 16 buttons but with only 1 I/O line is required, an analog input.…

The neopixel module lets you use Neopixel (WS2812) individually addressable RGB LED strips with the Microbit. Note to use the neopixel module, you need to import it separately with: import…

Tri-color LEDs contain three different LED emitters in one case. Each emitter is connected to a separate lead so they can be controlled independently. A four-lead arrangement is typical with…
