In this project, I'll make a small circuit capable of controlling a servo, it is a servo tester made out of a 555 timer IC.

This is a simple and easy designed circuit which is used to test the continuity. We know that continuity tester will used to test whether there is continuity or connection between two components. Here ...

Using this Pierce-oscillator circuit, users can test and verify the basic operation of a crystal in parallel-resonance mode. It allows the user to calculate and set the critical external capacitor ...
