I'm trying to assemble a circuit that will switch between 3 LEDs depending on input voltage. Electronic knowledge is very-very basic, but I'm working on it. I want 3rd LED to blink when circuit switches to it. Looks like I can accomplish with 555 timer.
So... Let's say input voltage is 0-9v
0-4v - nothing
4-6v - 1st LED
6-8v - 2nd LED
8-9v - 3rd LED blinking.
I'd like to be able to adjust points where each LED lights up (couple pots?). I want them to switch without overlap.
Is there some kind of voltage sensing relay or something like that?... Please, point in the right direction. Thank you.
