Art Meets Engineering: Using an Arduino compatible microphone to create light based on sound

     This weeks project was based on using good engineering principals to create art. I tend not to be a very artistic person in general, but when I thought about art, I tend to think of movies, and moving colors, so I can up with the idea for colors to move based on the "strength" of your voice. While the piezo can detect stuff such as taps, I needed a microphone to detect actual sound input, so I had to order one off of Amazon. In the parts diagram below, swap out the piezo for the microphone, but everything else is exactly what I used.

I connected all the regular LED's to digital pins 2-8 and 12, so that way I could just send a simple High/Low when I needed them on or off. I connected the RGB LED's pins to digital 9-11, so that way I could use the PWM technique to get analog results from a digital pin. I connected the final pin to ground. The microphone is connected to the 5V, ground, 0 digital pin, and the A0 analog pin to out put the digital and analog results.


The code was very simple for this project. It just included setting up the pins for all the LED's, and then setting some guidelines for what the maximum volume intake should be. I then created a series of If/Else statements, turning off/on the LED's as the inputted sound gets louder, showing that voice "strength" through the LED Line. The RGB LED has to constant values, (), and one non constant one () that is determined by the current sound value times 3. This changes the RGB LED's color too as sound increases.


While Im not usually the most creative person, it was fun letting my artistic side roam with this project. It was also one that got my friends super involved in the process with me, as I gave them all chances to scream into the microphone to see who could get the highest up (none of them did). There weren't any large setbacks (except for the microphone taking a week and a half to deliver).

IGME 480 Final Project Post: Road Shadows

     Project name: Road Shadows     Project members: Maxwell Sigrest     For my performance, I plan to let my video play, while I explain some of the technical choices behind what I did. I will explain the cache, edge and difference TOPs, how they work and how I implemented them into my work. I will show how the audio capture works, showing how notes of the same volume but different ranges effect the circle and edge movement.     My aesthetic is very calming and reminscient, made to make you remember 50 degree nights on the easy coast. The cars driving by and the trees, with the dusk background and there to make you remember summer nights and long car rides. The "shadows" are made by comparing frames between the video and boosting the brightness with a level. There is also audio capture, with it capturing low bass and middle notes, each effecting two different parts. The bass makes the circle in the center grow, and the middle notes effect th...

     Car crashes are never a good thing, and can put someone into serious harm or financial trouble. And while Manhattan is known for its skylines and beautiful attractions, they busy streets can cause a lot of car accidents. I wanted my visual to remind people to drive more carefully, be more aware of your surroundings, and to always make sure your are driving to the best of your ability. You can move the slider in the window to change the date of information. The information changing is the number of car accidents that happened in Manhattan on that certain day, and that is conveyed both with the number and the bar that moves. I started with a single container, with a slider inside. The slider will make the interactivity, with the container background showing all the visuals. The slider connects to a panel chop, which connects to two different math chops. One math chop changes the slider for the x-position, and the second one changes the slider range for the date-to-cras...

My data source is the Motor Vehicle Collision - Crashes data source from data.gov. This tracks motor vehicle collisions in NYC https://catalog.data.gov/dataset/motor-vehicle-collisions-crashes I will show the different types of collisions, results, and causes in a chart that can meaningfully show and tell the user about the likely hood and incident types and results. I would like to provide my data as a pie charts with different types of wheels as individual sections, or perhaps as different size cars in a bar chart. I will have a time slider where you can move it and data will change as time increases. Car accidents are no joke, and the outcomes are always never positive. My mood will be a gloomy one, with dark tones and colors, non-vibrant colors, and information and text that brings the user right to the point.
