Hello.
I would like to interupt a circuit several times a second. The circuit carries 24vac to a solenoid circuit under ground somewhere.
What I want to do is open and close this circuit several times a second so I can actuate and un-actuate the solenoid, causing it to buzz.
I need to find this solenoid and have been unable to do so. I hope the buzzing can help me home in on it.
What I am thinking of is perhaps something run off a 555 to trigger some sort of electronic switch for the 24vac.
Any ideas on chips for this purpose?
Thanks,
Alp
