VARIABLE POTENTIOMETER
General Description:
A 10k potentiometer is a type of variable resistor that is used to adjust the resistance in an electrical circuit. The "10k" in the name refers to the resistance of the potentiometer, which is 10,000 ohms (10k ohms). An adjustable potentiometer, 10K Potentiometer Module can open up many interesting user interfaces. Turn the pot and the resistance changes. 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.
Working Principle:
A 10k potentiometer module operates using a resistive track with a sliding contact (wiper) that adjusts resistance. The wiper's position determines the resistance between the wiper terminal and one of the other terminals. When the wiper is at one end of the track, the resistance between the wiper terminal and that end terminal is maximum (10k ohms), while the resistance between the wiper terminal and the other end terminal is minimum (0 ohms). Conversely, when the wiper is at the opposite end, the resistance values are reversed. Rotating the knob or shaft alters the wiper's position, changing output voltage or current. This versatility suits applications like volume control, light dimming, and motor speed adjustment.
