Step one for this project assembly is to measure your reactor and cut an appropriate length of acrylic to mount the LED’s to. Drill holes in the acrylic and mount the LED’s using an adhesive, I prefer hot glue. One tip to watch for is to make sure you keep the cathodes all on the same side.

Next we will solder all the leds together in parallel and attach a lead to the last set of leds.
Here we have a close up view of the controller with a test led mounted in the wire clip. We used an adafruit protoshield here and I recommend them highly
Here we have the lcd mounted just so things are clear for you.
Finally we connect power, load our program and connect it to our led bar. The source for this project can be found on the first page of this article. I don’t profess to be an amazing coder, but it gets the job done.
