I need to make a circuit that has a momentary switch and a light (30mW). When the switch is pressed, nothing should happen, but when the switch is released, I want it to pulse the light for a short duration (around 20 - 30ms)
I think I might be able to accomplish this with a capacitor and some 555 timers, but I'm honestly at a loss as to how to assemble it, or if it can be accomplished with just these components.
I feel bad asking for help with something that sounds so simple. But honestly, I'm pretty ignorant in developing even simple circuits. The affordability of Arduinos has really made me lazy and it's a problem. In the past, if I needed to make a light blink, I used $2 nano clone from China. Now I need to make a real circuit and I'm at a loss.
Any help would be much appreciated!
