Rotary Potentiometer – 10k Ohm

• Able to open up many interesting user interfaces
• Just turn the pot and the resistance changes
• Center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot

The Rotary Potentiometer – 10k Ohm can open up many interesting user interfaces.   Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot. Hook the center pin to an ADC on a microcontroller and get a variable input from the user.
