Connect the s port of the rotation portiometer electronic block to the a0 end of the arduino poll, and use the follow project to read its simulation value.thro UGH The SIMULATIN VALUE to SET The LED BRIGHTNESS.

const inst 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, OUTPUT);

}

void loop () {

Brightness = Analogread (A0); // Use a0 to read the electrical signal

Brightness = MAP (Brightness, 0, 1023, 0, 255);

// set the brighness of pin 9:

analogwrite (LED, Brightness);
