A potentiometer is a simple knob that provides a variable resistance, which we can read into the Arduino board as an analog value. Connect the three wires from the potentiometer to your board. The first goes from one of the outer pins of the potentiometerto ground.

In this example we use a variable resistor (a potentiometer or a photoresistor), we read its value using one anaput of an Arduino or Genuino . This example shows how to control a Analog Devices AD51Digital Potentiometer which communicates via the I2C synchronous serial . The first goes to ground from one of the outer pins of the potentiometer. Let’s say you want to control FlightGear’s throttle with Arduino. You need a sensor that can measure variable values within a certain . In this tutorial you will learn how to use a potentiometer with and without Arduino board to fade an LED.

You will also learn how to use analogRead() and map() . Connect the potentiometer to pins A 5V and GND. Tags: analog Arduino Tutorials code learning lesson potentiometer Tutorial . A potentiometer is a perfect demonstration of a variable voltage divider circuit. Arduino Uno; 1x LED; 1x 330Ω Resistor; 6x Jumper Wires; 1x Potentiometer .
