Sound-Responsive LED Painting (on the relatively cheap)

This instructable will show you how to make a triptych painting with LED lights that respond to music. I will be honest and say that this isn't the first project like this, but this is how I made this one and it's relatively cheaper than other projects I've seen like this, which ended up with an overall cost of $2000+ or something. This project cost me maybe $60 total, if that, although I did have some of the required items already on hand and the two major components were on sale on Amazon at the time of my purchase.

I didn't take pictures as I went, so I apologize that all the photos were created in MS Paint.

Here's my final end result:

Step 1: Gather Your Materials

Materials Needed:
-Muslin (fairly thin or see through for the lights)
-Square wooden dowel rods, ¾ in, straight (make sure they are not too warped or bent). Use a lightweight wood but not a “fake” wood which would split. I got mine at Home Depot
-freezer paper (for the stencil)
-acrylic paint
-iron
-paint brushes
-wood glue
-staple gun (optional)
-hot glue/hot glue gun
-This LED light set
-This IR controller (This company has other IR controllers but they may not have three ports. I’m sure there are other IR controllers that work the same way; just make sure that there’s a correct number of ports for the number of panels you are making. This is the one I used)
- extra connectors
-printer/paper
-tape
-solder and soldering gun
