> I am trying to control multiple LEDs but I am not quite sure on how to adjust my code accordingly. I have a master code that runs an RTC clock module and a light sensor to an LED. I have separated both my codes. I was able to control an LED simply by connecting it to ground and pin 9 on an Arduino board. After running processing for just that, I was able to turn the LED on/off. Once I tried to combine it with my master code, I believe the problem was that I am using port = new Serial(this, "/de…
