Here's a simple demonstration of controlling the speed of a blinking LED with a potentiometer...
And the code:
/* Setup pins */
int potPin = 2;
int ledPin = 13;
int v = 0;
/* Set LED to Output */
void setup() {
pinMode(ledPin, OUTPUT);
}
void loop() {
/* Read from potentiometer */
v = analogRead(potPin);
/* Turn LED on */
digitalWrite(ledPin, HIGH);
/* Wait relative to where potentiometer value is */
delay(v);
/* Turn LED off */
digitalWrite(ledPin, LOW);
/* Wait again */
delay(v);
}
