Understanding LED lights


The group CRZY decided to try to understand LED lights better by using an Arduino starter kit. They’re different projects you can do that involves engineering, and it is relatively¬†easy. We decided to make a color changing lamp that uses LED’s. We used a breadboard, Arduino Uno, LED’s , 220 OHM resistor, 10 KILOHM resistor, a phototransitor, and gels. We didn’t find anything that could help us. The instruction were talking about stuff we didn’t even understand.I also think there were pieces missing. Hopefully we will have better luck in the future.
