Step 9Strap it all together
At this point, I used the cable I made to connect the 2 boards together and then used hot glue and zip ties to attach everything to the back of the drain board. For now, the board from Modern Device is receiving 5 volts of power from the Arduino, but I bought an external D cell battery pack just in case. I ended up not using the external battery pack.
Now, to really complete the display portion of the costume, I needed to write some code for the Arduino to accept commands via USB from the laptop and then drive the LED driver board accordingly. My plan was not to store any image patterns in the Arduino, but rather accept images from the laptop and then light up the LEDs based on that. The sample code that Paul provides on his site made for both a great way to test to make sure that everyting was wired properly and as a base for my own code. Lucky for me, when I ran his sample code on my setup, it worked the first time.
