Hi I have used the following example to in my relay circuit, but wanted to know how I could add a potentiometer to control the switching interval.
so my light does the following with the below code.
int led = 2;
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
How do I add a potentiometer to control the light intervals?
Thanks
