I have a project in mind that uses el wire. The power supply I have is an inverter with a push button. When you push the button the first time it lights up the el wire. The second push flashes the wire at a low frequency. And the third push runs it at a higher frequency. Last push turns it off. Opening the power supply up it looks like the push button is a momentary button with just two connections. I’d like to set up a microprocessor so that it would control a number of these el power supplies. But I have to confess that I am very much in the dark about how this push button works and how emulate it’s function. Can someone out there help? Thanks.
Without a schematic for your inverter, the easiest way I can think of to do this would be to connect a relay or transistor across your button and then have a microcontroller briefly turn the relay or transistor on to emulate a button press.
