The 555 Timer IC is a popular 8-pin Integrated circuit chip that can be used in a variety of timing and pulse generation applications. The IC can operate in three different modes such as Astable, Monotstable and Bistable, because of which it can be adapted into many types of circuit designs like time delay circuits, pulse generation circuit, oscillator circuit and much more. The below list from Circuit Digest consists of a huge collection of 555 Timer circuits with neat circuit diagram and practical DIY hardware explanation enabling you build your own 555 Timer projects.
LEDs are commonly used in electronic circuits, and with the LEDs, you can make many things which are interesting.

LEDs are commonly used in electronic circuits as they consume less power, are easy to use, and have a long lifespan. In this tutorial, we will learn how to build an LED ON and OFF circuit using 555 timer IC and BC557.
Required ComponentsBefore we get started, let's understand the components we will be using in this circuit.
555…
Working with electricity can be a daunting and life-threatening task if you are a beginner in the electronic/electrical field, and things can go very wrong when electricity is not properly handled, which is why safety must come first in order to avoid injury, before starting work on an electric box and AC mains one need to verify that there is no AC leakage voltage.…
Audio content has come a long way over the past decades, from a classic tube amp to modern-day media players, technological advancements have changed the way digital media is consumed. Among all these innovations, portable media players have become one of the first choices among consumers, because of their vibrant sound quality and long battery life. So how does it work, and…
In this project we build a boost converter circuit using a 555 timer IC. Boost converter is a non-isolated type of switch mode power supply that is used to step-up the voltage. In other words, it gives a higher output voltage compared to the input voltage. The circuit is very similar to a buck converter we designed for controlling motor and LED strip which is used…
In this article, we will make a buck converter using 555 timer IC and a IRFZ44N N channel MOSFET and use it as LED dimmer circuit or as a motor speed controller circuit. This circuit is basically a simple power electronics DC-DC Buck converter which can be used to step down voltage, its efficiency results in better battery life due to reduced heat generation making it a…
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 from these, there are other popular circuits like 555 timer IC as a switch and police hooter that we have talked about previously. Adding to the list,…
Upon hearing a siren of a nearby police vehicle, one might think about how this tone is being generated. You’ll be surprised to know that the brains behind these tones are not a microcontroller but a humble NE555 timer IC. If you know a little about electronics then you must have heard of 555-timer IC and its 3 very popular circuits the astable multivibrator, the…
If you are a hobbyist or have keen interest in electronics circuits, you must be familiar with 555 timer IC and its three popular circuits - Monostable multivibrator, Astable multivibrator, and Bistable multivibrator. Guess what, we can even use this IC as a switch. This is the type of button that holds its state i.e. on the first press, it switches…
Motion sensor circuits are there on the Internet for quite a while now. These circuits are mainly used to drive AC load (like lights, fans) in home automation or IoT projects. It is also very common in manufacturing industries, like on conveyor belts where the presence/position of a particular object has to be detected.
So, in this tutorial, we are…
The multivibrator circuit is very popular and useful in the field of electronics, and it’s the most basic circuit that you will know about while learning basic electronics. The multivibrator circuit can be divided into two categories: the first one is known as the monostable multivibrator, and the second one is known as the astable multivibrator. But in this project, we will…
