Below section covers a list of simple microcontroller projects to learn and work with the concepts of various microcontrollers and architectures. These microcontroller based projects are covered with detailed explanation of working of hardware, circuit diagrams, software and codes.
Microcontrollers are widely used in various industries, electronic products, automobiles etc.. to perform computing or logical operations. With this huge importance the demand of microcontrollers in industries is prominent and hence as electronics engineers it is important for us to learn how to use them. There are a large number of semiconductor companies manufacturing a variety of microcontrollers, the most popularly ones are 8051 microcontrollers, AVR microcontrollers, PIC microcontroller, TI Microcontrollers, Arduino, Raspberry Pi etc.
This tutorial describes how to make an automatic water dispenser from Arduino and an ultrasonic sensor. This tutorial describes how to make an automatic water dispenser using an electronic diagram, a code snippet, a list of things, and a demonstration of how to make your water dispenser work.

Robotic Arms have proved themselves useful and more productive in many applications where speed, accuracy and safety is required. But to me, what’s more than that is these things are cool to look at when they work. I have always wished for a robotic arm that could help me with my daily works just like Dum-E and Dum-U that Tony stark uses in his lab. These two bots can be…
In previous article of Getting Started with LabVIEW, we have seen about LabVIEW and how it can be graphically programmed and executed in computer (software level). Now in this article we learn about How to Interface LabVIEW with Arduino Board.
Requirements
To interface LabVIEW with Arduino, you require the following software’s and hardware’s,
LabVIEW…
In previous tutorial, OLED is interfaced with ESP32 using SPI communication which uses 5 pins. In this tutorial, we interface 16x2 LCD with ESP32, using only 2 pins, with the help of I2C communication. It reduces number of pins used by ESP32 so that more number of ESP32 pins remain free for interfacing different sensors.
What is I2C…
Arduino would have been the first board for many hobbyists (including me) and engineers out there when they started with electronics. However, as we start building more and dig deep we would soon realise that Arduino is not industry ready and its 8-bit CPU with a ridiculously slow clock, it does not give you enough juice for your projects. Hopefully though, we have the new…
One of the fascinating things about system on chips (SoC) like Raspberry Pi is their ability to serve as web servers to host websites and other online applications. This webserver serves host files when request is made from the client end. Today, I demonstrate How to Setup a Webserver on Raspberry Pi and Install a Wordpress Website which can be accessed by any device on the…
In this DIY session, we make an Arduino Motor Driver Shield to drive DC motors, stepper motor and Servo Motor. Compatible with Arduino UNO and Arduino Mega, this motor driver shield can operate 4 DC motors or 1 stepper motor and 2 servo motors at a time. Here two L293D Motor Driver ICs are used for driving motors and an 8-bit shift register for controlling…
Fire Alarm Systems are very common in commercial building and factories, these devices usual contain a cluster of sensors that constantly monitors for any flame, gas or fire in the building and triggers an alarm if it detects any of these. One of the simplest way to detect fire is by using an IR Flame sensor, these sensors have an IR photodiode which is sensitive to IR light…
In this tutorial we design a system to read the RFID cards using MSP430 and RFID Reader. RFID stands for Radio Frequency Identification. Each card has a unique ID and this makes it a perfect choice for many authentication applications, like in offices, shopping malls and in many other places where only the person with authorization card is allowed to enter inside. …
Have you ever thought about a speaker which can be controlled by your voice!!! What if we can control our home appliances this way and make these appliances smarter? Voice assistants becoming more popular as we are heading towards an era of AI and IoT based systems. You have heard about Google Assistant, Apple Siri and Amazon Alexa. These all are Voice based AI systems, what…
Reed switch is used in many of the real-life applications such as magnetic door switch, laptops, smartphones etc. In this article, we learn about Reed Switch and guide you to Interface a Reed Switch with Arduino.
Reed Switch
Reed switch is basically an electrical switch which is operated when a magnetic field is brought near to it. It was invented by W. B.…
Be it a boring afternoon, a monotonous job or a lonely long drive FM radio stations have always kept us entertained. While on the contradictory it should also be agreed that sometimes these FM stations get very boring with the RJ blabbering irrelevant stuff or some bugging advertisements and that might have kept you guessing why you can’t have your own FM Broadcast station…
