Laser Security System Problem On YouTube.
I have been trying to figure out how to build Kip Kay's Laser Alarm and I ran into some problems. When I attach the battery to the circuit the alarm goes off. I tried to adjust my potentiometer but that had no effect. I am useing a 2N3904 transistor a 5k potentiometer from Radio Shack, www.radioshack.com a photo cell also from Radio Shack, www.radioshack.com and 1000uf capacitor
