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 timer IC is an integrated circuit (chip) which is used in a variety of timer, delay, pulse generation, and oscillator applications. 555 Signals and Pinout (8 pin DIP) Figure below shows the ...

Long and longer timeout periods are frequent goals for the ubiquitous 555 timer. Generally, this is accomplished (albeit unreliably) by unusually large electrolytic timing capacitors. However, here ...

With a 555 on the BOM, you never know what you’re going to get. With 40 of the versatile timer chips in a build, you might just get something completely unexpected, like this 555-based eight-bit ...

Applications of commercially available integrated timers, including the NE/SE555, are fairly limited when used in their monostable mode. This is due to their inability to function with all types of ...

Sometimes the best inspiration is limitation. The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparators, a voltage ladder, and a ...
