Set @Holiday = Valentines_Day

Circuits / Muhammad Bilal

This Instructable can be modified for any major holiday, however my students wanted to focus on something they could do for Valentine’s Day. In this design, students’ hands are the conductive material that complete the circuit when they “high-five” the two halves of the heart. When the circuit is complete, the “space” input triggers a

WaveShare Motor/Servo Driver With Micro:bit

Motor Projects / Muhammad Bilal

This Instructable will show you how to use a WaveShare motor/servo board with a micro:bit to power multiple servo motors. This board will make it possible to run more powerful servo motors than the micro servo motor that you can run directly from the micro:bit. Technical information for the WaveShare board is here: https://www.waveshare.com/wiki/Motor_Driver_for_mi… There is
