My project is a 3-D printout of my name with LED lights that change colors. The materials needed to complete this were:

3-D printed name
3 LED lights
red wires
black wires
battery
battery holder
switch

The tools needed were 
3-D printer
multiple pliers
solder machine

The most challenging part of the project was getting it done on time. We had a very small time frame to finish. Also I had to switch my project from an electric hand to this. There weren't any times where I didn't expect it to work because it is a pretty straight forward project. Once I was finished my wire snapped so one of the lights didn't work but Mr. Umekubo fixed that. I thought that at the end product was really cool because I got to see my project come to life. I learned how to solder and make a circuit which I didn;t know how to do any of that before. If I had more time or resources I would make it HUGE with tons of lights. I had to try new techniques and strategies to make it work but Mr. Umekubo really helped me a lot.

Here is a video of my project:

Isabel and I created an American Flag that plays the National Anthem with LED lights. We are not completely finished with our final project. Isabel and I had fun creating this because we got to try to make the song to have ur sound correct and we like our flag. We used a board to cut out the flag and we used the LED lights and the hummingbird program. Next time we would add more to it and work faster because we ran out of time a few times.
