Electronics Projects

In this category posts about electronics projects will be available. In that posts, i will design some circuit and explain the working of that circuit.

Short circuit

Overcurrent or Short Circuit Protection

In a short circuit condition, a large current flows which are never intended. In this case we might damage our power source, our electronics devices and every associated component. It also risk of fire due to excessive heat. To avoid the short circuit, we need to design a circuit and connect it in between our …

Buck converter and its application

In the project of dc dimmer circuit we saw that how we can step down the voltage using PWM. But in that circuit there is a problem of high voltage peak. That can destroy the sensitive electronics devices. For that kind of electronics devices there is another step down circuit called buck converter. Buck converter …

Smart Security alarm circuit

In this project we will design a smart security alarm circuit which will detect and create unwanted activity and alert us using a buzzer. In this project we will design the circuit from the prospective of securing the bikes. So, here unwanted activity is shocks. To detect the shocks we can use piezoelectric disk. For …

Battery charge indicator

In a battery powered electronics devices you often need to know the charge status of the battery. In this project we will create such circuit which can indicate the percentage of left energy in the battery. For indicating the charge percentage we will use LEDs. To drive the LEDs according to battery voltage, we can …

single phase soft starter circuit diagram and working

Some electrical component comes with inrush current problems (like motor, capacitor, buck/boost converter etc.). It basically means that these devices draw very large current during starting. Let’s say you have connected these devices with some safety circuit and power for power it up. But because of its inrush current as you power it, power supply …

Digital counter display

In this project you will learn how to make a digital counter display which will show you number of pulse applied to its clock pulse. This counter will count up to 999 but you can add more digits to increase count number. We will see this circuit using BCD counter and 7-segment hex decoder first …

Clap Switch for light (home automation)

In this project we will make two clap switch circuit for AC appliances such as light and fan, using which we will be able to turn it on or off using your clap. It will be ‘ON’ on two claps at interval of less than 500ms and turn ‘OFF’ on one clap. For this we …

DC Motor speed controller circuit

You often need to dim the brightness of the led, led strip, or control the speed of the DC motor. We can make A simple DC dimmer using NE555 IC and a few more components. Using this circuit you can control the brightness of LED strips or the speed of a DC motor efficiently. You …
