My name is Dannielle and I go to Promise Academy High School. For my starter project I created a voice changer. It allows you to change the sound of your voice into a high pitch, low pitch, vibrating voice, and a robot voice. For my main project I created an LED necktie that lights up when you talk or make a noise. I chose these projects because they both seem like different projects that would amaze anyone and even myself if I completed it. Both projects were pretty challenging since I have no experience in engineering at all, but I overcame that challenge by completing both of my projects.
Main Project – LED Necktie
For my second milestone I added a different color to my necktie. When my necktie is on but there is no sound, the color of the neopixels are a light purple. I was able to change the color to a light purple by changing the strip color in the code to 3,0, and 5. These numbers allow me to add the color I want my neopixel to light up in. I added a battery pouch to the back of my tie. I also added lace to my necktie to add a dash of my personality in it.
My first milestone for my LED necktie was to actually get my tie to completely work. My tie consists of 1 flora board, 15 neopixels and one mic. A flora board is an arduino compatible micro controller. Neopixels are individual color pixels. When I speak or make a noise, the mic sends a signal to the flora board that tells the pixels to light up a certain way. One problem I had with my necktie was the connection between the neopixels and the flora board. I noticed that the conductive thread was not tightly secured around ground and positive, so I had to resew those two over so that there would be a good connection. For my next milestone, I plan to add different colors to my necktie and maybe even patterns.
