Crowbits-Potentiometer

What is Crowbits-Potentiometer?

Crowbits-Potentiometer is an analog input module, it acts like a variable resistor, it controls your circuit by adjusting the resistance in the whole circuit.

How does it work?

The main component of the potentiometer module is a rotary potentiometer. The hat on the rotary potentiometer allows you to adjust it manually by hand.

If you rotate the hat clockwise, the resistance of the potentiometer grows, the current goes through the whole circuit and becomes smaller.

Bigger resistance = smaller current.

If you rotate it counter-clockwise it will go the exact opposite, lowering the resistance and leveling up the current.

Use cases

Think about a light dimmer that you have in your room, it’s a great use case.

You can connect the potentiometer to a light source (LED for example) and by rotating it you’ll be able to control the brightness of the LED, how cool is that?
