Learn to read analog input signal from potentiometer with Arduino Uno.

Code :
// Code Example - Analog Input
// Read potentionmeter value from Analog pin 0 (A0 of Arduino )
// Display the value (0-1023) on the serial monitor
// After uploaind the code, open serial monitor from Arduino IDE ar 9600bps

// Arduino Basic by Atrobo Technologies.

int pot_value ; // using a variable "pot_value" to store the value of the pot

void setup() {
Serial.begin(9600); // start Arduino serial communication at 9600 bps
}
void loop() {
pot_value = analogRead(0); // use analogRead() on analog pin 0 to read its value
Serial.println(pot_value); // using Serial.println() to send the value to the monitor
}

// end code
