Fishtank Daylight Timed LED - Part 2

Wade Cantley

With a little help from the Pi4J project site, I setup for a simple LED to flash following these plans 

http://pi4j.com/example/control.html

 

So this should help with the software logic of making the LED flash.  Right now I only have a red LED but I will replace it with the IR LED as soon as it comes in the mail.


Also, I realized I lost my power supply so that is coming as well.  So the stuff ordered includes a power supply and the IR Diode LED light and sensor which thankfully there was a small kit that included both and didn't send quantities of 50.

Very simple circuit.

p18 = > 180 ohm resistor -> LED - > Ground
