The lab this week was a great learning experience for my introduction to physical computing. Since I come from a background of software engineering, I am used to testing my work with little consequence. Physical computing is NOT the same. I am sorry, my poor green LEDs. I did not mean to burn you and your brothers out. Eventually, I was able to get the current voltage for the LEDs via resistors and choosing a lower voltage from the Arduino chip. I hope it gets easier!
