Step #1: Make the connections
Use the breadboard (or protoshield) to connect one leg of the photoresistor to Analog Input 0, and the other leg to +5v. Then, take the 10K resistor and connect one leg to GND (ground) and the other to Analog Input 0. Also, I wired an LED to Digital I/O pin 13 to show when the laser beam is broken. Hook the negative end of the LED to ground as well.
