Story

When we initially started this project, the idea was to create a box that had rgb LEDs, which color could have been changed with a potentiometer and turned on and off with buttons, with a buzzer to play sound with certain actions.

Due to complications with the limited number of of pins on an Arduino, and difficulty of charlieplexing, we decided to scrap the rgb LEDs and change things up a bit. We ended up deciding to get 6 normal LEDs in 3 different colors, and use a potentiometer to cycle through the lights. They can be turned on and off with three buttons, and the lights can be reset by knocking on the bottom of the box, which activates a clapper.

This is what our wiring looks like:

Just kidding :3

We started off by setting up the LEDs on practice breadboard, before moving on to the main one

Then the potentiometer was installed along with the buzzers.

The enclosure was made from cut pieces of wood that was held together with wood glue and tape.

One of the difficult parts of this project was making the buttons and LEDs fit in the enclosure properly. There was a lot of trouble soldering and attaching the wires to the breadboard so that the wires would not come undone, or that they would fit.

Another challenging aspect was understanding how to code with charlieplexing. It took way longer to work with than we would have liked, and wiring it correctly so that other components could function properly as well also proved difficult, and ultimately unsuccessful.
