This type of circuit is ideal for use in a "push to operate" system for a model displayed at EXHIBITIONS. A visitor cans push a button to start a model's mechanism, moving, and the mechanism will from automatically switches off after a set time.
The circuit diagram of the 555 monostable circuit is given as follows.
- resistor value R and the capacitor value C are unspecified. The values of these components determine the length of time that the monostable output is in the high state, and they may be calculated using the equation below
- T = 1.1RC or R = T/1.1C
