• Test pin

Steps

1. Connect the potentiometer terminals to the Arduino test pins.
2. Connect the middle terminal of the potentiometer to an analog input pin of the Arduino.
3. Write an Arduino sketch to read the value of the potentiometer.
4. Check the potentiometer datasheet to determine the voltage range.
5. Use the value read from the potentiometer to control an LED or a motor.
6. Test the potentiometer to ensure that the value changes correctly.
7. Adjust the potentiometer to obtain the desired value.
8. Test the complete project to verify that everything works correctly.

Example code

int potPin = A0; // pin analogico 0 int val; void setup() { Serial.begin(9600); } void loop() { val = analogRead(potPin); Serial.println(val); }

Mini project
