In the figure we have a basic oscillator with inverters obtained from TTL, CMOS or other gates. The graph on the side allows to find the frequency depending on the resistor and the capacitor.
Bipolar transistors are types of general use like BC548, while the power MOSFET can be of any type...
We found this circuit in an old documentation. Its purpose is to turn on warning lights when the...
This simple humidity alarm circuit includes a timed warning oscillator whose time is set to R4....
