Electronic is fun to learn, especially if you can learn it by building your own circuits. 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.
Voltage Multipliers are the circuits where we get very high DC voltage from the Low AC voltage supply, a voltage multiplier circuit generates the voltage in multiple of peak input voltage of AC like if the peak voltage of AC voltage is 5 volt, we will get 15 volt DC at the output.
Generally, transformers are there to step-up the…
The features of the digital products are growing enormously which triggers the frequent usage of smart phones in several applications. Thus the battery backup time is getting decreased. It will be fun to build a Power Bank for Mobile Phone as spare charging source for emergency purpose which is also portable.
Previously we have made…
In simple language, Tone Control Circuit is the circuit, using which we can control the output of audio device. To control the output means we can control the Volume, Treble and Bass of the Audio output. So, to achieve this aim we have to control the output frequency. If we can control output frequency than our aim is achieved!
To control the output…
Be it an ordinary high school project or a mind-blowing arcing project, a Tesla Coil is always fun to build and will definitely make your project look cool and attractive. A Tesla Coil is a simple coil that creates a high voltage electric field in the air when a small input power (9V) is provided, this electric field is strong enough to glow small light bulbs. This…
In this project, we are going to Control the Speed of Dc Motor Wirelessly Using IR or TV Remote Control. Here we are not going to use any microcontroller. We have used basic components along with 555 Timer IC to complete this task. This circuit can control the DC motor speed in 5 different levels and any IR remote like TV/DVD remote etc can be used to control it.

In this project, we will make an 8-channel Motor Driver Module Circuit for motors based applications. In this circuit, we have designed a PCB for driving DC or stepper motors. By using this motor driver board we can operate 8 DC motors or four 4-wire stepper motors at a time. In this board, we have used few three pin screw terminal blocks and burgsticks, connected from the…
The objective of this project is to convert 220V AC supply in to +12V and -12v DC supply, that is why it is named Dual Power Supply as we get positive and negative 12v power supply at the same time.
This can be achieved in simple three steps:
Firstly, 220V AC is converted into 12V AC by using simple step-down (220V/12V) transformer. Secondly, output of this transformer is given to…
In this project, we are going to make a TRIAC dimmer circuit for AC Appliances. Here we are not going to use a microcontroller. We have used basic components to complete this task. In this project, we will use Triac to control the brightness of the AC bulb with a IR TV Remote. You can also control Fan speed with your TV remote using this Triac Dimmer circuit.

You have seen many LED torches in the market, mostly use white LEDs as they provide good brightness and light. Today we are making the low cost and highly efficient Simple LED torch light Circuit which allows your battery to live longer, for this we are using a 4049 hex inverter buffer IC. By the help of this IC, we are making a voltage multiplier circuit which doubles the…
The term digital in electronics represents the data generation, processing or storing in the form of two states. The two states can be represented as HIGH or LOW, positive or non-positive, set or reset which is ultimately binary. The high is 1 and low is 0 and hence the digital technology is expressed as series of 0’s and 1’s. An example is 011010 in which each term…

There are many ICs available to drive a 7 Segment display like IC 4026, 4033 etc and we have covered driving 7-segment using 4026 and using 4033. In this tutorial we are going to drive 7-segment display with IC 4511. This CD4511 IC is basically a BCD to 7-Segment decoder/driver IC, using which you can convert a binary number into a decimal number on the 7-segment display.…
