Monostable mode 555 timer, also called a one shot, responds to a low trigger voltage by giving a single high output for a period of time set by the values of the timing capacitor and it’s resistor. The output then drops back low and stays there until triggered again. It’s got one stable state (low), so it is called monostable.

I really like this easy to use 8 battery universal charger. Made a few videos with it.
Briefly pressing the button lights the LED for a period of time set by the capacitor and it’s charging resistor.
