Re: Hooking LED to DS
Keep in mind that different LED's operate at different current settings. The digital output signal pin produces 5V of power when turned "on". Find an appropriate 5V LED (most of them are 5V) and then do some math to ensure you get the proper resistor to place inline with the LED, based on the current requirements for the LED. Many places you can order LED's from will have them available with the matching resistor as well.
