SunFounder Thales Kit for Raspberry Pi Pico, Release 1.0
The functions of the potentiometer in the circuit are as follows:
1. Serving as a voltage divider
Potentiometer is a continuously adjustable resistor. When you adjust the shaft or sliding handle of
the potentiometer, the movable contact will slide on the resistor. At this point, a voltage can be output
depending on the voltage applied onto the potentiometer and the angle the movable arm has rotated
to or the travel it has made.
2. Serving as a rheostat
When the potentiometer is used as a rheostat, connect the middle pin and one of the other 2 pins in
the circuit. Thus you can get a smoothly and continuously changed resistance value within the travel
of the moving contact.
3. Serving as a current controller
When the potentiometer acts as a current controller, the sliding contact terminal must be connected
as one of the output terminals.
