Potentiometer (POT)
Potentiometer (POT)
Also known as POT. A potentiometer is a variable resistor
Understood as Potential-meter, where potential means voltage
Good explanation from Physical Computing
Used as
2-legged as normal variable resistor
3-legged for voltage divider
From Physical Computing: Potentiometer legs 1-2 or 2-3 as variable resistor, Tinkercad link
