I've been playing with LED circuits for a while now, familiarizing myself with Arduino, but no I'm looking to do something with a bit more advanced circuitry.
I'm planning out a motorized target range for use with a BB gun. I just need some conceptual advice on how to do certain things. The main idea is that a target will get hit, fall back onto a microswitch, this should energize a motor to push the target back up and add a point to a score on a 7-seg display, plus there'll be some LED's involved somewhere. The part I'm not sure about is the delaying of the motor. I want the button to be part of the same circuit as the motor to save myself a pin on the Arduino because I plan to have a bunch of these all hooked up to a single nano. So I need the motor to work something like this: Target hits switch -> delay 3 seconds -> energize motor -> auto disconnect motor after 2 seconds.
Never mind the rest of the circuit, I'll probably start building this with just the motor and switch hooked up. I'm unsure of how to introduce these delays just using components. I've looked up basic delay circuits (NOTC, NCTO), but they don't suite my requirements. If it's less hassle to just use up a pin on the Arduino then I'll do just that.
