Note: if your screw terminal doesn't want to grab the wires, try again with a different screw terminal. These parts seem to be pretty delicate and I went through a few of them before I found one that grabbed adequately.
Decide where you'd like your Circuit Playground controller to be mounted and measure the distance from that point to the placement of your first LED strip. Cut four wires to this measurement (plus a couple inches for slack) to connect to the Circuit Playground.
It's easiest to match the colors on the LED strip connectors, so we're using black, green, yellow, and red.
Solder the four wires to the Circuit Playground:
Bring the wires in from the back of the Circuit Playground rather than from the front. This will make the board fit snugly in the case without having the wires in the way.
If your lights don't come on and act as expected, here are a few things to try:
- Make sure the wires going into your screw terminal are still tightly attached. These like to pull themselves out!
- Check to be sure you've connected the Circuit Playground to the "IN" end of the LED strips. If you're connected to the "out" end you'll need to cut off your connectors and switch everything around.
- Be sure your power supply is adequate for the number of LEDs you're driving. If you're getting a brown-out in part of the strip (the LEDs look dim and the colors are off), you can "inject" power into any of the exposed power wires between the strips by adding more power wires into your screw terminal and connecting the power in several places.
This is a little trickier than it looks, so take your time! It's easiest to screw the lid on when the case is upside down so the buttons stay in place.
