I went shopping for parts and brought voltage regulators, resistors, and heaps of alligator clips to connect to what is controlling the sound. I went all over the place to get the alligator clips, I started at bunnings because I didn't want to walk to Jaycar. They did not sell them so they pointed me to JA Russel across the road. JA Russel also had none and pointed me to Jaycar. So I ended up walking to Jaycar anyway. Once home, I started working on the Arduino program to hopefully be able to test it by tomorrow.
