On Off button w NE555

659

15:35:54

This circuit is able to turn on and off a load by using the ne555. Configured in this way it will also prevent from fast on off to save the load (for example a lamp). The delay between the change of state is of about 0.65 second.
The three 5kOhm resistors are only to visualize the internal limits of the 555. If you want to change the voltage you will also have to change the 20kOhm or the capacitor. Or if you want to increase the delay between the possibility of state change you will have to increase the resistor value or the capacitor value.

Amazing but change the capacitor value from 47uf to 10uf

Good tip but by doing this I will reduce the 0.65s time before a state change :)

Very nice thanks for sharing! Mine is a much simpler approach just to play around with the resistor and a single push button to change the current direction ;)
