perfboard

Once we got our LED circuit working it was time to build the circuit that create the sound.  This was slightly more complicated because it involved using a chip, called a 555 timer, which when configured with various resistors would output sine waves.  After much trial and error we were able to not only build the sound circuit, but also combine it with our LED circuit. Now that we have a working prototype, the next step is 1. design the box or enclosure that will house the circuit, and 2. figure out how to move from the breadboard to a perfboard.  Soldering all of our connections on a perfboard is essential since it creates hard connections.  It is definitely going to prove to be quite the challenge however.
