- // These constants won't change. They're used to give names to the pins used:
- const int analogInPin = A0; // Analog input pin that the potentiometer is attached to
- const int analogOutPin = 9; // Analog output pin that the LED is attached to
- int sensorValue = 0; // value read from the pot
- int outputValue = 0; // value output to the PWM (analog out)
- void setup() {
- // initialize serial communications at 9600 bps:
- Serial.begin(9600);
- }
- void loop() {
- // read the analog in value:
- sensorValue = analogRead(analogInPin);
- // map it to the range of the analog out:
- outputValue = map(sensorValue, 0, 1023, 0, 255);
- // change the analog out value:
- analogWrite(analogOutPin, outputValue);
- // print the results to the Serial Monitor:
- Serial.print("sensor = ");
- Serial.print(sensorValue);
- Serial.print("\t output = ");
- Serial.println(outputValue);
- // wait 2 milliseconds before the next loop for the analog-to-digital
- // converter to settle after the last reading:
- delay(2);
