Target Practice with Arduino and Laser Pointer

So let’s say you’re an imperial stormtrooper. You’re constantly gunning for rebel scum but when you’re face-to-face with the enemy you couldn’t hit the broadside of an AT-AT with your laser rifle. Worry no more! In this instructable, we’ll be making a target practice circuit with an Arduino, LEDs, and a photoresistor so you can practice your aim with a laser pointer or even a flashlight.”
