Capacitive Touch Sensor to activate Shaved Door Poppers

I'm trying to figure out a way to code my Uno to sense very rapidly and shut off after a second in order to imitate the pulse of a door lock actuator. I figure the touch lamp code could be altered in such a way to perform the task, I just don't know how. Ideally I would like to be able to run 4 sensors with 4 outputs, all separate. Any suggestions?
