There are many situations when our circuit design has two power sources such as an adapter and a battery or it can even be two other power supplies from two different outlets. The requirement of the ...

In many IoT applications, there are situations where the sensor data needs to monitor continuously, and the simplest way to do that is by enabling an ESP8266 webserver which serves an HTML webpage; ...

To measure the heartbeat we need a pulse sensor. Here we have selected SEN-11574 pulse sensor which is easily available on online or offline stores. We used this sensor as there are sample codes ...

We are very much familiar with our television sets, DVDs, MP3 players, music systems and many other device that are controlled by using IR Remote. There are many types of remote controls available for ...

Before explaining PID Controller, let's revise about Control System. There are two types of systems; open loop system and close loop system. An open loop system is also known as an uncontrolled system ...

Li-ion cells are becoming the most desirable energy storage system for more and more applications with every passing day due to their high energy density and other benefits these cells have to offer.

LoRa is getting increasingly popular with the advent of IoT, Connected Cars, M2M, Industry 4.0 etc. Because of its ability to communicate to long distances with very less power it is preferably used ...

The Number Plate Recognition API is easy to understand and simple to integrate into various projects. It eliminates the need for complex image processing and machine learning on the user’s end, making ...

To start with let us understand what these OLED displays mean. The term OLED stands for “Organic Light emitting diode” it uses the same technology that is used in most of our televisions but has fewer ...

The inductor is one of the major passive components in electronics. The basic passive components in electronics are resistors, capacitors and inductors. Inductors are closely related to the capacitors ...

A stepper motor is a type of DC motor that works in discrete steps and is used everywhere from a surveillance camera to sophisticated robots and machines. NEMA 17 stepper motor provide accurate ...
