The potentiometer symbol comprises a resistor symbol with an arrow in the middle. The more you turn the knob, the more youll reduce the volume. In the example circuit above, the program simply displays the analog value on the serial monitor. It makes 0 difference electrically (because the resistance between the wiper and the lead is shorted out), but it just emphasises that you didn't "forget" to connect the third lead, you intentionally are using the potentiometer as a rheostat. just use one group of three pins and ignore the other group. V, in this case, represents the supply voltage of the circuit. NOTE THAT: GND pin and VCC pin are interchangeable How It Works Terminal 2 is joined with the wiper. And, as others have suggested, it's typical to connect the "open" end of the pot to the wiper, which slightly reduces the wiper noise and has other beneficial effects. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. The greater the resistor value the smaller the current will flow. Potentiometer usually has 3 pins: GND pin: needs to be connected to GND (0V) VCC pin: needs to be connected to VCC (5V or 3.3v) Output pin: outputs the voltage to Arduino's input pin. Circuit. A potentiometer and a rheostat may seem similar but are not. There are various types of knobs in the market constructed to rotate the shaft of a POT and make them more suitable.
