b) A 5.2V microcontroller has 150mW of power that it can continuously supply to all 15 of its pins. If all 15 of the pins are connected to LEDs with a voltage drop, VD of 2.4V what is the minimum resistance that should be in series with each LED to prevent the microcontroller pins from burning out.
