To help you with that, Circuit Digest provides you with a list of popular Electronic circuits and Electronic projects with well illustrated circuit diagram and detailed explanation for a complete do-it-yourself experience. All projects are tested and verified with a working video for a hassle free learning experience. Whether you are an expert or beginner in electronics, we have something interesting for all of you. Below is our huge collection of 200+ free electronic circuits that you can build today.
After watching and experiencing turning off and on our household water pump manually, it was really hectic and frustrating. It happened many times when you stay alone at home and while using the bathroom, the overhead tank got emptied and you were hassled. Even the opposite happened when you turned on the pump and forgot to switch it off, causing heavy water and…
While making a customized RGB LED set up at our home, basically it was a bunch of addressable 5v LEDs the WS2812, but unfortunately, we didn't have a high current power source to light them up properly. Since there was a lot of them, it required around 9 Amps of current to lighten up at full brightness. This led us to design one Power Supply for this purpose, as well…
Recently, we thought of building a simple FM receiver circuit, so, like always, we started googling for possible circuits that can be used to fulfil our requirements, and as expected, we found a lot of circuits on the internet, but the question remains, how good or useful will they be when we put those circuits to the test? Because just like us, we found a lot of…
Switch Mode Power Supplies (SMPS) are one of the most generally used AC-DC Converters on the market as they accept 110V/230V AC as input and convert it to a desirable DC voltage level, making them useful for a wide range of applications. These are omnipresent, from smartphone chargers to lab bench power supplies to medical tools. We've already developed a few SMPS…
Styrofoam and polystyrene have been one of the most efficient methods of model making amongst the maker community, thanks to their lightweight, extremely low cost, and the ease with which they can be crafted into some breathtaking pieces of artwork.
But working with Styrofoam often requires a lot of heated element tools that get…
In this article, we will be learning about the features and working of the XL4015, which is a 5A 180KHz 36V Buck DC to DC Converter. Here we will desolder all the components from the module, completely reverse engineer the schematic and make the PCB from it, so that we can order the components and make the PCB ourselves. The XL4015 DC-DC buck converter is a versatile…
A power bank is a portable rechargeable battery that allows you to connect to an external charging source when you don't have access to a wall charger. The market for power banks has exploded, making it one of the most popular electronic products available. However, such a fantastic device comes with an equally astounding price tag. Fortunately, we will go over a…
We'll be making a 12V 2000mAh Li-ion Battery pack in this post. We'll start by designing a 3s battery pack, then connecting the BMS to it to execute all of the BMS's functions. Li-ion cells are increasingly used as battery packs for many applications due to their high energy density and rechargeable characteristics. However, we must link a Li-ion cell with a BMS to…
Nowadays we can’t even imagine a world without power. Even an intermittent power failure is so inconvenient. As we depend on electricity in many important areas of our life, it is important to take persuasion against power failures and that’s where the inverter plays an important role. There are multiple types of inverters in the market,…
In this article, we will be learning about the features and working of a 3S 6A lithium Battery Management System or BMS along with checking out the components and the circuitry of this module. Furthermore, we have done complete reverse engineering of the module by removing all the components from the PCB and measuring all the PCB traces with the multimeter. For…
Switching Mode Power Supply (SMPS) is an interesting component that uses a compact design within a space of one or two inches and could be easily soldered in the PCB. It is a hot cake in this electronics industry and there are lots of companies that manufacture this thing. How nice it would be if we can build a standard SMPS circuit that could be fitted in a limited space…
The buck-boost converter is a DC-DC converter that uses the same concept of both the buck and boost converter but in a simplified combined circuit. As the name implies, the main feature of a buck-boost converter is its capability of making the output voltage constant even though the input voltage drops below the output voltage that means this circuit can work both in…
