Sorry about that! Here's what I have currently!
int ledPin = 9; // LED connected to pin 9
const int buttonPin = 2;
int buttonState = 0;
int fadeValue = 0;
void setup() {
pinMode(9, OUTPUT);
pinMode(buttonPin, INPUT);
}
void loop() {
buttonState = digitalRead(buttonPin);
if(buttonState == LOW) { // if button isn't pushed
// fade in from min to max in increments of 5 points:
for(int fadeValue = 0 ; fadeValue <= 255; fadeValue +=5) {
// sets the value (range from 0 to 255):
analogWrite(ledPin, fadeValue);
// wait for 30 milliseconds to see the dimming effect
delay(30);
}
// fade out from max to min in increments of 5 points:
for(int fadeValue = 255 ; fadeValue >= 0; fadeValue -=5) {
// sets the value (range from 0 to 255):
analogWrite(ledPin, fadeValue);
// wait for 30 milliseconds to see the dimming effect
delay(30);
}
}
// hold the brightness if button is pushed
else if(buttonState == HIGH) {
fadeValue +=0;
analogWrite(ledPin, fadeValue);
}
}
