My current materials consist of: <\/p>\n\n\n\n
- Arduino<\/li>
- Several RGB leds<\/li>
- Materials from the RBE 1001 kit (including Electret microphone and photoresistor)<\/li>
- Sparkly red, sparkly blue, and plain blue tulle<\/li>
- End-emitting fiber optics<\/li><\/ul>\n\n\n\n
After experimenting with several Arduino programs, I have chosen two that I will focus on: color fading and brightness fading. My initial ideas for this project were to have user input trigger a wave of light across the wall, however, I have found it difficult using an Electret microphone without the module, due to the more complicated op amp circuit I would need to setup. I then experimented with a photoresistor as an input trigger, with the idea that a user’s shadow across the project would shroud the wall in darkness, causing a wave of colors to flow along the fiber optics. My current progress regarding the electronics of it all is a color-fading program, that goes through a sequences of colors, fading between each. I also have a separate program that utilizes the photoresistor to correlate the brightness of the RGB led, with the led glowing brighter the less light the photoresistor sees.<\/p>\n\n\n\n

<\/figure>\n\n\n\nThe following is my progress regarding the fiber optics. I had gotten end-emitting fiber optics and tried two methods to create side-emitting fiber optics. I first attempted to sand the sides, however came to realize that too much sanding prevented light from coming through at all and practically made those portions useless. I then tried cutting little nicks into the length of the fiber optic using an exacto knife, which proved very successful. I will be using both the side-emitting and end-emitting fiber optics for my wall of vines, with an emphasis on the side-emitting ones.<\/p>\n\n\n\n

<\/figure><\/li><\/ul>\n\n\n\nLastly, with regards to the fiber optic weaving and the overall architecture of the project, I found that the natural shapes of the fiber optics were too stiff to bend to recreate the characteristics of vines. I am planning on purchasing a series of malleable crafting wire from Amazon, as well as birch branches from Michaels to use as a vine base for the fiber optics, similar to the metal bonsai trees. I will also be acquiring a new microphone module in a few days to attempt again a sound-based user input. By the next week, my goal is to have a finalized Arduino code with user input and a foundation for the vine and leaf placement.<\/p>\n","protected":false},"excerpt":{"rendered":"
After proposing my three concepts to the class, I found that the majority of my peers were interested in the wall of vines proposal, in which I model a miniature wall covered in snaking vines using fiber optics. The first thing I began working with was gathering some sample fiber optics and creating simple Arduino… <\/p>\n
