Where can I get a laser and a sensor? (preferably cheap) Answered
I'm looking for a laser that is button activated and a sensor that reacts to the laser.
Basicly I want to put the laser in the barrel of a broken bb gun and make the button so that when you pull the trigger the laser goes off. Then I want to make a circle with the sensor in the center and when you hit it with the laser you hear a sound.
Now I am wondering where I can get a laser and a sensor that responds to it. the laser can be visible or invisible I don't really care. Also does the sensor respond to any laserbeam or is this specific?
Thanks in advance,
