What’s a Potentiometer, you ask? It’s actually a variable resistor, like the dimmer switch for your lights at home. The resistance is from 0 to 200 Ohms. As you increase the resistance by rotating the dial, you consume more power at the potentiometer. This reduces the power available to the LED or the motor in the circuit. Result: a dimmer LED and slower motor.
The Potentiometer Cube is just one part of a circuit. Add a battery to power your creations, a motor to make them move, an LED to light them up, and a switch to take control!
