I am an absolute beginner in electronics. So far I have created a circuit with 2 LEDs and 2 SPST pushbuttons, each controlling a different LED. Very simple, you should get the idea without me drawing a circuit.
I've been trying to figure out how to add a third pushbutton, which would control both two LEDs at the same time, without altering the functionality of the two existing two pushbuttons.
Is it even possible to achieve this with 3 SPST pushbuttons, without adding any other components? If not, I am interested in learning what would be the simplest design to achieve this. Thank you.
