Measure Light with Arduino (LDR vs Phototransistor showdown!)

Learn how to control an LED using two different kinds of light sensors and an Arduino Nano (you can use Uno as well). We'll cover using a phototransistor and an LDR (light dependent resistor or photoresistor) and why a phototransistor is a better and more modern choice.
