Preliminary Model
As an introductory project to Arduino and circuitry, I wanted to explore creating patterns with individual LEDs. This first model utilizes 9 LEDs which all had to be individually wired. The frame is made from poplar and laser cut styrene.
Final Model
For the final model, I used a pulse sensor to create a heart rate monitor using a LED and buzzer. Wiring and programming individual LEDs becomes clumsy, so for the final prototype I used a LED strip instead.
Thanks for viewing!
