A buck converter circuit (step-down converter) is a DC-to-DC switching converter that steps down voltage while maintaining a constant power balance. The main feature of a buck converter is efficiency, which means that with a buck converter on board, we can expect extended battery life, reduced heat, smaller size, and improved efficiency. We previously made a few simple Buck…

WhatsApp is one of the most popular cross-platform messaging tools that is used by a vast majority of people. Even though its recent privacy policy update came as an unpleasant surprise for many people, the user base WhatsApp still holds good and nearly 2 billion people use WhatsApp today. This huge user base has attracted many medium and large-scale businesses to use…

GSM modules are interesting to use especially when our project requires remote access. These modules could make all actions that our normal mobile phone could do, like making/receiving a call, sending/receiving a SMS, connecting to internet using GPRS etc. You can also connect a normal microphone and speaker to this module and converse on your mobile calls. This will…

A digital pulse oximeter and heart rate sensor is an electronic device which can measure the heart rate of a person by measuring the difference between oxygen rich and oxygen less blood. Not only heart rate, this device can also measure the concentration of oxygen in blood. So in this article, we will interface the popular MAX30102 pulse oximeter and heart rate…

Noise pollution has really started to gain importance due to high population density. A normal human ear could hear sound levels from 0dB to 140dB in which sound levels from 120dB to 140dB are considered to be noise. Loudness or sound levels are commonly measured in decibel(dB), we have some instruments which could measure the sound signals in dB but these meters are…

In one of our previous projects, we interfaced SX1278(Ra-02) based LoRa module with Arduino and established communication among them. This was a very simple project and can come in handy for various applications. But what it can't do is establish communication with the internet for modern-day IoT applications. So in this project, we will be using the HPD13A which is…

A Power supply unit is a very commonly used tool by most engineers during the development stage. I personally use it a lot when experimenting with my circuit designs on Breadboard or to power up a simple module. Most of the digital circuits or embedded circuits have a standard operating voltage of either 5V or 3.3V, so I decided to build a Power supply which can supply 5V/3.…

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.

Energy Monitors, whether covering the entire apartment or deployed to monitor just one appliance, provide a way for you to keep track of your consumption and make necessary adjustments. While they are increasingly becoming available on the market, the maker in me still feels it will be a great idea to build a DIY version that could be tailored to meet specific personal…

Function generator or waveform generator is an integral part of electronics and used to produce various kinds of waveforms like a sine wave, square wave, Sawtooth wave, etc. We have already designed sine wave generator circuit, square wave generator circuit, and sawtooth wave generator circuit. Now in this tutorial, we will show you, how to design a…

Prepaid Electricity Energy Meter is a good concept in which you can recharge its balance, like we do in our mobile phones. In this project we are building a automated system by using Arduino and GSM module. You can recharge the electricity balance through this system, just by sending a SMS. It can also disconnect the home power supply connection, if there is low or zero…

We previously interfaced Joystick with Arduino UNO to understand how it works and controlled four LEDs on its left, right, up and down movement. In this project we will use the same Joystick as Gamepad or game controller to play any computer games which requires left, right, up and down movements. To play games which requies more control options, two or more joysticks can be…
