Thanks for helping out so much, since I am using Miles Tag shooters, I think I will be using Milestag Protocall. Since Im just a caveman, but I am trying to learn as fast as I can. I will be lining the control collars for my zombie actors with 4 receiver and led sections, and when the zombie is hit with the IR beam, lights turn on, a buzzer starts and the zombie is destroyed, until the person resets the collar. I have the 56kHz IR emmiter and the matching receivers for this project, just need the brains for the collars for this to work. I will be gearing up 6 people at a time to enter a building and survive an attack from 100 plus zombies. Since I am in the northwest, there is a huge zombie following and everyones tired of paintball and airsoft. I am going to start out small, but putting the guns together from my stock of converted airsoft guns is going faster than expected.
