Controlling high power (or high number of) LED’s with an Arduino…

A while ago I posted about my bench lights, and have gotten a number of request for schematics and code. I’ll gladly put the code up, but I also wanted to explain what I did so that others can create their own, or at least change my design up as they wish. The transistors I’m using are TIP122′s. You can find the data sheet here. They will switch a lot of power, but keep in mind, they need to have adequate cooling if you are going to push them hard. Always remember, fire = bad.

I covered the basic schematic for a few LED’s in the video above, but if you have any questions, feel free to post them in the comments and I will answer as quickly as I can.
