(Suitable for ages 8 years and over)
The MonkMakes Slider for micro:bit allows you to interact with your micro:bit by sliding a control left and right.
The board uses a 10kΩ linear variable resistor (pot) to output a voltage between 0 and 3V that can be measured in your micro:bit programs using one of the micro:bit connections as an analog input.
The kit includes the Slider for micro:bit itself plus a set of 5 alligator clip leads. Comprehensive instructions with example projects are provided as a free download.
Note: BBC micro:bit available separately.
