The DEMO
Connect the S port of the rotating potentiometer electronic block to the end A0 on the Arduino board and use the following procedure to read its analog value. Set the brightness and darkness of LED by simulation value.
Const int led = 9; // the pin that the LED is attached to
Int brightness = 0; // how bright the LED is
Void setup () {
// declare pin 9 to be an output:
PinMode (led, the OUTPUT);
}
Void loop () {
Brightness = analogRead (A0); //use A0 to read the electrical signal
Brightness = map (brightness, 0, 1023, 0, 255);
/ / set the brightness of the pin 9:
AnalogWrite (led, brightness);
}
