A circuit shown below is a 555 monostable circuit, powered by a 9 volt battery. The circuit has be drawn on 'Crocodile Technology 3D' software and then animated (using graphics/animation software). A circuit can be constructed with this software and tested on screen. Faults can then be corrected before the circuit is manufactured with real components. This saves time and money. Furthermore, Crocodile Technology 3D allows the circuit to be seen and tested in three dimensions and rotated into almost any position. This makes it much easier to understand the layout of the components and how the circuit works.

The motor only illuminates when the push switch is pressed. It works once and then stops. The switch must be pressed again for the bulb to light.

Increasing the value of the resistors and capacitor extends the time the motor's shaft rotates.
