This circuit works in real time and is easy to construct on a breadboard plus the circuit layout is clean and easy to follow. This 5V example also works at different simulator speeds once the proper transistor capacitor values have been adjusted.
* The SPST switch is in the NO position.
* Flick the SPST switch to the NC position and WAIT A FEW SECONDS for the simulation to begin.
* If the SPST switch is in the NC position when you power up the circuit, WAIT A FEW SECONDS or simply shake your smartphone or tablet to begin the simulation.
* Alternatively, press one of the push buttons located near the power source and the simulation will begin immediately.
