Arduino Final Project

For my final Arduino project, I wanted to expand on the LED musical cue project and create an experience around the song that I chose. I was inspired by the artwork for "Me and Your Mama" by Childish Gambino (below). I really loved the contrast of light and dark in the photograph and the woven headdress around the figure really appealed to me. So I decided to create an enclosure that was similar in style and woven.

 

I also wanted the lights to flash blue and white to simulate the lighting in the cover art.

I started with the enclosure which I cut from chicken wire. I cut six pieces and made a roughly 3.5x5 inch box 

Next, I took cotton twine and wove the pieces through the squares of the chicken wire. Once all of the pieces were woven I connected them with zip ties.

Before I closed the box, I built the bread board with the lights and circuits connected to the arduino. I placed the arduino and bread board in the enclosure and surrounded it with stuffing and a cut crystal candle holder to better reflect the light. I ran the USB cable through the weave and closed the enclosure.

This is the finished product with the musical cues.

Arduino + Firmata

This week's project required us to use Firmata to either control a function in Processing with Arduino or control a function on Arduino with Processing. I chose to use build an example given to us in class- using beat detect in the Processing Minim library to control LEDs on my breadboard. 

You can find the source code and the original project instructions here.

Step 1:

Connect the GND to the negative rail on the breadboard. Arrange the LEDs on your breadboard and connect 220 resistors to each of the LED anodes.

Step 2:

Connect wires from the negative rail to each of the cathodes on the LEDs.

Step 4: 

Connect the anodes on each LED to 2, 12, and 8 on the digital pins of the arduino on the left side of the resistors.

Step 5:

Upload the Standard Firmata to your Arduino. Add your audio file to the BeatDetect file in Processing by dragging and dropping into the Processing GUI. Change the .mp3 file name to the name of your file and run the code.
