Our Project
Me and a partner had to create a project with and Arduino Board and coding. We spent many weeks learning about electricity and how circuits work. We then had to learn how to code and think of a project to do. We thought of a cross walk and street light. The multi-colored LED changes from red, green, and yellow. Once the light hits yellow push down the green button and the LCD will change from " Don't walk" to "walk". The green LED will turn on and the red LED will turn off.
Code
Concepts
Voltage-(V) potential energy drop across a component of a circuit
Circuit- a closed loop made of conductive material with a power source
Curent-(I) the electricity that flows through a circuit
Resistance-(R) a measure of how much resistance the current encounters

Reflection
Overall this was one of my favorite projects this year. There were many ups and downs. Our first idea was to have a DJ table where a pedometer would change the songs between multiple buzzers, but we found that the program wouldn't be able to support that. Then we went to just coding the notes of just one song into the buzzer and having the lyrics play on the on the LCD, but the song that we wanted to play didn't save on the computer. After all that, we scratched the entire idea and did a cross walk inspired by the annoying crosswalk that keeps my friend from getting to the bus stop every morning. Once we got that going, we had a couple more days left to add something new. We decided to add a stop light that would change and only allow the cross walk to go when the light turned yellow. The stop light turned out very well, considering that we had to create the yellow because there was not yellow peg on the light.
