  • I have created three control modules for 24 Christmas light circuits (controlling about 10,000 LED lamps) For each module, I made another board that incorporate 8 solid state relays. The Darlington driver easily controls (switches) the solid state relays (bought from Spark a Fun) that I soldered to the female end of outdoor 18 gauge green extension cords. Having learned from the first one, cut the cords so that you have 3-4 feet of lead to work with. I mounted everything into a plastic Thermous brand lunch pail that I sealed th holes for the handles. I s filled a hole in the side of the bottom of the box for the leads to exit and sealed everything. I had to write the program on my MacBook for various lights and program them. If I decide to change something, I just make the changes on my MacBook, then carry it out to the controller and overwrite the existing program in less than a minute. These work Awesome!

  • Can the Darlington driver switch 120v AC to cycle LED Christmas light strings on and off?

No public wish lists :(
