Hi; I am new here but hope to get some help. I need a timer for an air cannon used for a haunted house to control valve timing when triggered by a presser mat. The mat is NO and I should have a relay output for the valve. I would like to pulse the relay when someonr steps on the mat for .1 to .5 seconds and then wait for 1 to 5 seconds befor it can be trigered again. I was hoping to use a 555 timer and tryed to get a MK111 adjustable interval timer kit to work but cant get it to hold for a few seconds befor it can be triggered again.
Can this be done with one timmer or will I need two?
Can someone help with a circuit that I can build with 555 timers?
Thanks Andy
