Used in a variety of timer, pulse generation, and oscillator applications, the 555 was designed in 1971 by Hans Camenzind. A favorite for many engineers, the 555 is still in widespread use due to its ...

Chris Gammell from the blog The amp hour and Analog Life is running a 555 timer IC design contest. EDN’s Mike Demler wrote it up on his blog yesterday. So Mike or Chris asked me to do a mention on ...

This project demonstrates the construction of a voltage doubler circuit using a 555 Timer IC, 1N4001 diodes, and 1nF capacitors. The 555 Timer IC is configured in astable mode to generate a square ...

If you are an electronics hobbyist then you must have heard about the 555 timer IC and its 3 popular circuits viz. astable multivibrator, bistable multivibrator, and monostable multivibrator. Apart ...

In this project we are going to design a Simple Time Delay Circuit Using 555 Timer IC. This circuit consists of 2 switches one for start the delay time and other for reset. It also has a potentiometer ...

Have you ever seen or heard about Dummy Alarm? Now we are explaining you about Dummy Alarm. It is almost similar to an alarm, where as it flashes high power red LEDs for every 5 seconds. The main ...

The 555 timer IC has been reinvented—again. Signetics introduced the enormously popular chip back in 1971, and it quickly became a big hit. Myriad application circuits have used it throughout the ...

A stopwatch is a timer that is used to measure an event anywhere from milliseconds to several hours. We can start and stop the count of the stopwatch at any instant and it can also be reset to zero to ...

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 ...
