Before we review the circuits though, lets take a look at the basic anatomy of the timer. A diagram shows that the circuit consists of two comparators, which share a common voltage divider. Voltage ...

The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the most widely used ICs due to its reliability and flexibility.

In the classic configuration and most variants of the astable 555 multivibrator circuit, the timing characteristics are based on the charging and discharging of a capacitor. However, it can be argued ...

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.

The 555 timer is one of the most versatile integrated circuits available. It can generate PWM signals, tones, and single-shot pulses. You can even put one in a bi-stable mode similar to a flip flop.

A close look at the circuit reveals that it consists of a discrete D-type flip-flop formed by NAND gates U1a-U1c. The setup delay of the LS series gates is around 10 ns. This causes the settling ...
