Well the solenoid would go off everytime the trigger would be pulled. Which could be up to 20 times a second. So the eye would need to be able to keep up wiht it. The Sensor can be placed where it is opposite. but most made for this purpose is only used on one side.

sry been gone a lil while. But anyway it would be detecting Sphere objects. They would be paintballs. They are 68 calliber and filled with a thick milky liquid. they are like plasticy (hard) on the shell. Just curious how to make one. It needs to be able to run off of 1 or 2 9v batteries. And connect to a solenoid. And if it dont sense a ball the solenioid wont shoot. ty

Hey guys. I was just wondering how you could find parts to make like a sensor that could hook up to a solenoid, so that the solenoid dosent shoot unless the object is in the sensors eye or sight.
