Yes, a newbie to the forum but looking for some help with what amounts to probably a simple configuration based on what in read searching through the forums here. I'm looking for help and validation on a quick project I'm working on.
I have two devices that I need to pair in such a way that when I hit a button, I need a 12v circuit and a 3v circuit to be charged for say 5 seconds. There will be a switched 12v power supply (meaning it's battery powered with an on off switch on the battery pack). The 12v portion of the circuit will need about .8A while activated (so assume 1A with in rush). The 3v portion will need around 800mA.
My initial thought was a single throw single pole switch, a timed 12v relay of some sort, and a step down module to go from 12v to 3v for that portion.
So my question for the group is whether I'm on the right track, and if so, does anyone have suggestions on components? There are literally thousands out there. I would like the timed relay to have something like a potentiometer to allow for more precise timing adjustments if needed. Anyone know of a single small module that can do both? I found several small step down modules on Amazon but I had a hard time finding a relay module that allowed for the constant 12v supply with a 12v signal provided by the switch to activate the timer on the relay and switch the normally open circuit.
Thanks in advance.
