In this article you will learn how to build an optical theremin using a 555 Timer IC. You will learn the functions of the pins on the 555 chip that are used in this build. You will learn that when the ...

You can use a microcontroller to build a clock. After all, a clock is just something that counts the passage of time. The only problem is that microcontrollers can’t track time very accurately. They ...

A monostable multivibrator, also known as a one-shot pulse generator, is a circuit that generates a single output pulse in response to an external trigger input. When built using a 555 timer IC, the ...

A timer circuit that turns on a pump for a short time every five minutes can be easily made using the famous 555 IC. Unfortunately, it's almost impossible to avoid using electrolytic capacitors to ...

First introduced in the early 1970s, the 555 timer integrated circuit is arguably one of the most popular ICs ever made. Rediscover the iconic 555, how it works and its many uses with the new Book of ...

A monostable multivibrator is a timing circuit that produces a single output pulse when triggered. Using the 555 Timer IC in monostable mode, this project aims to design and simulate a circuit that ...
