By textbook definition, Embedded Electronics can be defined as a system that “Integrates Hardware circuitry with software programming techniques to provide real-time solutions”. From age old pocket calculators to advanced automobile and security devices the applications of Embedded System continue to show a strong progress.
In this section we will discuss about the various embedded controllers and embedded development platforms including, but not limited to Arduino, Raspberry Pi, NodeMCU, ESP32, Microchip, AVR, ARM, MSP430, STM32, STM8S, Nuvoton etc. It also updates the readers with latest Embedded News and technology trends to help them plan and design their Embedded Projects with ease.
We know in offices, shopping malls and in many other places where only the person with authorization card is allowed to enter the room. These systems use RFID communication system. RFID is used in shopping malls to stop theft as the products are tagged with RFID chip and when a person leaves the building with the RFID chip an alarm is raised automatically. The RFID…
If you are looking for a beginners guide on “How to start with 8051 Microcontroller”, here in this article I will show you how to work with 8051 microcontroller practically. I am not going into detail of “What is 8051 microcontroller”, or “How to write a c-program” etc., but the scope of this article is to tell about the hardware and software which are needed to…
Ultrasonic sensors are great tools to measure distance and detect objects without any actual contact with the physical world. It is used in several applications, like measuring liquid level, checking proximity and even more popularly in automobiles to assist in self-parking or anti-collision systems. Previously, we have also built many Ultrasonic Sensor…
In this project we are going to design a circuit for measuring temperature. This circuit is developed using “LM35”, a linear voltage sensor. Temperature is usually measured in “Centigrade” or “Faraheite”. “LM35” sensor provides output based on scale of centigrade.
LM35 is three pin transistor like device. It has VCC, GND and OUTPUT. This sensor…
In this tutorial we are going to design a 0-99 counter by interfacing two seven segment displays to ATMEGA32A Microcontroller. Here we count events based on number of times button is pressed.
Before moving ahead, let's understand what is a seven segment display. A seven segment display got its name from the very fact that it has seven…

While LPG is an essential need of every household, its leakage could lead to a disaster. To alert on LPG leakage and prevent any mishappening there are various products to detect the leakage. Here we have developed an Arduino based LPG gas detector alarm. If gas leakage occurs, this system detects it and makes an alert by buzing the buzzer attached with the circuit.…
Seven segment displays are important display units in Electronics and widely used to display numbers from 0 to 9. It can also display some character alphabets like A,B,C,H,F,E etc. In this tutorial, we are going to learn how to interface a 7 segment display with 8051 microcontroller. We are using AT89S52 microcontroller from 8051 series.

A line follower Robot is a very simple robot that follows a line, either a black line or a white line. These types of robots are very simple to build and are often the first choice for beginners who are getting started with robotics projects. Basically, there are two types of line follower robots: one is a black line follower, which follows the black line, and the…
The interfacing of a 16x2 LCD display with 8051 microcontroller is very popular and one of the most important in embedded systems programming. This tutorial will explain the complete LCD interfacing of 8051 C program, circuit connections, and coding strategies in a program with the use of the AT89S52 microcontroller.
The display units are the most important output devices in embedded…
Microcontrollers are integral part of embedded systems. A microcontroller is basically cheap and small computer on a single chip that comprises a processor, a small memory, and programmable input-output peripherals. They are meant to be used in automatically controlled products and devices to perform predefined and pre-programmed tasks. To get a better idea of what…
Thermometers are useful apparatus that have been used for a long time for temperature measurement. In this project, we have made an Arduino based digital thermometer to display the current ambient temperature on a 16x2 LCD unit in real time. It can be deployed in houses, offices, industries, etc., to measure the temperature. We can divide this Arduino…
