 Tutorial: Measure the potentiometer values

 The function of this sketch is to read the rotary potentiometer values
 and display them in percentage on your computer

 Connections from the Rotary potentiometer to the Arduino:
 • potentiometer GND pin → Arduino GND pin
 • potentiometer out pin → Arduino A0 pin
 • potentiometer VCC pin → Arduino 5V pin
*/

//Define the variable PotentiometerRead to Analog Input Pin A0
#define PotentiometerRead A0

//Commands inside void setup run once
void setup()
{
 //Start the serial monitor at 9600 baud rate (9600 bits per second)
 Serial.begin(9600);
}

//Commands inside void loop run forever
void loop()
{
 //Read the analog value from the potentiometer out pin and assign it to the variable Read
 int Read = analogRead(PotentiometerRead);
 //Convert the value to percentage
 int percentage = map(Read, 0, 1023, 0, 100);
 //Print to serial monitor
 Serial.print("The Potentiometer at ");
 Serial.print(percentage);
 //Print "%" to the serial monitor and then add a new line
 Serial.println("%");
 //wait for 100ms
 delay(100);
