== Introduction ==

The Rotary Potentiometer Module produces analog output between 0 and Vcc (3.3V DC with LinkNode D1 ) on it’s “OUT” connector. The angular range is 300 degrees with a linear change in value. The resistance value is 10kΩ.

== Wiring & Running ==

The module is connected to the base shield J9:

Sensor Signal --> LinkNode D1 ADC0

This example uses ADC channel 0 to get the value of the rotary potentiometer output voltage.

Open the Arduino IDE serial monitor ( BAUD 9600 ) , you can see the module output voltage.

== Simple Code ==

void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
}

void loop() {
// put your main code here, to run repeatedly:
int value = analogRead(A0);
float voltage = (value) * (3.3/1024.0);
Serial.print("Output Voltage (Unit:V) : ");
Serial.println(voltage,2);
delay(300);
}
