  1. Warmup – 23FEB2012 Arduino This one is for practice. I have paper if you need it. PB0 Suppose there is an LED on PB0. Assume that the forward voltage, Vf, for the LED is 2 V. Find R to limit the current through the LED to 10 mA What power will be dissipated when the LED turns on? R

  2. Power Dissipated
