Electronic Circuits

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.

A binary counter is a chip designed to count the number of pulses or events that occur in digital circuits. These chips memorize the events and show the count of events at output port. The chip memorizes the event and shows the output in binary code, hence the name BINARY COUNTER.  What binary counter does it each time a pulse is appeared at clock pin, it counts it and…

We use many different types of communication in control applications to control home appliances, industrial appliances, and other type of automation. There are two types of communication that is we generally use - one is wired and other one is wireless. In wireless communication we transmits signal wirelessly, like using radio frequency (RF) and in wired communication in…

XOR or EX-OR gate is a digital logic gate, designed for arithmetic and logical operations, Every electronic student must have studied this gate is his/her career. This gate is mainly used in applications where there is a need for mathematical calculations. So in calculators, computers and many digital applications use this gate.

H-bridge is the circuit in which voltage can be applied across the load, in either of the direction. These circuits are frequently used in robotics, especially for the DC motor. Voltage can be applied in either direction to rotate the DC motor forward or backward. DC motor further move the robot or any robotic system, forward or backward.

You must have seen different kinds of decoration lighting patterns. In this LED chaser circuit, we have created an interesting LED blinking pattern by using a 555 timer IC and Counter IC CD 4017.

 

Required Components CD 4017 Counter 555 Timer IC 150, 1K, 10K Resistors 10K Variable Resistor 10uf, 100nF capacitor…

NOT gate is a digital logic gate, designed for arithmetic and logical operations, every electronic student must have studied this gate is his/her career. This gate is mainly used in applications where there is a need for mathematical calculations. So in calculators, computers and many digital applications use this gate.

This car parking assistant can protect your car from any damage while reverse parking. It indicates the distance of car from any object and raise an alarm when it reaches close to the wall or the object and needs to be stopped. This car parking sensor circuit is quite easy and uses few commonly available components which are listed below.

In present time almost all the people are familiar with robots. Robots play a very important role in human life. Robots are a machine which reduces the human efforts in heavy works in industries, building etc. and makes life easy. In Our previous Projects we have made some robots like line follower, DTMF controlled robot, gesture controlled robot, computer controlled…

IR Transmitter and IR Receiver are commonly used to control electronic devices wirelessly, mainly through a remote. TV remotes and AC remotes are the best example of IR transmitters. TV generally consists of TSOP1738 as the IR receiver, which senses modulated IR pulses and convert them into electrical signal. Here in our circuit we are building IR remote and its receiver.…

Sometimes we face a common problem when making any project related to battery or power supply - we don’t know about battery is charged or discharged. To test battery there is one common method which is using voltmeter that is available in the Multimeters. But here we have developed this battery monitor circuit to test the battery charging status. In…

In this tutorial we are going to show you how to use a Push On-Push Off button by controlling an LED using it. For this, we are using a Self-locking Power Micro Push Button Switch. The switch we are using has double pole option or it’s a DPDT (Dual Pole Dual Throw) type switch. It has the capability to be used as both “normally open” and “normally closed” type switch.…
