Since we're talking about the 555 internals and what can be done with it, here's how to use it as a 12V 200ma  driver, for power FET gates as an example. Or maybe a 12V LED strip.

It could also be used to make a Arduino to 10V PWM driver for 30 and 60 watt LED power drivers from MeanWell, etc.

Can the capacitor of the circuit be non-polarized? What is the difference between a polarized cap and a non-polarized one?


You can always use a non polarised capacitor in place of a polarised one, but not necessarily the other way round.
