The function of the 555 timer is mainly determined by two comparators. The output voltage of the them controls the state of the RS flip-flop and the discharge tube. It also contains 3 working states.

The 555 multivibrator circuit has become a default choice of many hobbyists and even professionals in the past 50 years. Its pair of equations for frequency and duty cycle easily gives ...

This project is a PCB design for an Astable Multivibrator circuit using EasyEDA. The circuit is designed to generate a continuous square wave output, with an LED flashing at a specific frequency. It ...
