Lesson 25 Silde Potentiomenter
module
Introduction
In this lesson, let’s learn about the use of the slide potentiometer.
What is slide potentiometer?
The similarity of the Slide Potentiometer Module and Potentiometer Module
lies in: holding three terminals; changing the resistance between the
changeable terminal and one end by changing the position of the slider.
When the difference is: the Slide Potentiometer usually has a larger power
(and size) and can be used directly as a load or connected in serial in the
circuit of the load for current limiting. The potentiometer has a smaller
power and size, and generally used for voltage sampling in signal circuit.

Operating steps
1. First, we need to prepare the following experimental materials:
1 * microbit
1 * microbit expansion board
1 * USB cable
1 * Silde Potentiomenter module
- Several Jumper wires
2. Now connect the slide potentiometer to micro:bit.
