Need suggestions for alternating power in circuit? Answered
I am working on a little circuit that uses a potentiometer to send a pulse to a piezo, I would like to install another pot with different settings and automatically alternate the pulse between the 2 pots. Power would need to be redirected to each potentiometer alternating for approx 15-20 sec.
So when I power on, there will have a 20sec pulse using potentiometer #1 then 20 sec using potentiometer #2 and so on...
The circuit works on a 1.5v to 4.5v dc power source. There could also be a delay between the 2 different pulse.
What would you suggest using as the switching hardware ... ic ... chip? The circuit is working right now but uses only 1 potentiometer with 1 set pulse, I just want to add another pot.
Thanks for all inputs, looking forward to hear from you.
