I have a button in my Electric car, with a small LED in it. By default when I turn on the car, the LED in the button lights up. Pushing the button turns the LED and the Fake engine noise OFF. The button is controlling a Fake engine sound generated at low speed. But I do not want this functionality and now I manually have to push the button everytime. There is no way to change the default state.
What I would like is that when the LED turns ON, it should simulate that I push the button to turn it off. Preferably with a small delay to prevent multiple button presses. And I also imagine that it could be self powered by the current going to the LED.
So I was wondering if anyone could help me design a small circuit or point me to a ready solution?
I tried to search but most I found includes microcontrollers, and I want the circuit to be as small and simple as possible as I want it to be near the button, and not needing external power.
