This tutorial will cover those wonderful blinky things, LEDs. We’re going to cover how to calculate the current going through an LED and in the mean time introduce two important laws of electronics, Kirchhoff’s Voltage Law and Ohm’s Law. We’ll begin by performing experiments that will demonstrate how voltage and resistance affects current and then prove those results with a little math.
