Assignment 10.1

Post date: Jul 17, 2010 3:48:46 AM

For this one I used a potentiometer connected to analog pin 1 to control the brightness of an LED connected to digital pin 9.

Here's my code:

int val = 0;

int ledPin = 9;

int potPin = 1;

void setup() {

//twiddle your thumbs

}

void loop() {

val = analogRead(potPin);

val = map(val, 0, 1023, 0, 225);

analogWrite(ledPin, val);

delay(30);

}

Here's a Fritzing pic of my circuit:
