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.
Every electronics engineer loves to break electronics things and explore what is present inside it. Recently I opened an LED TV and found ARM Chip inside it. ARM based microcontrollers are heavily used in various types of embedded products and systems. They comprise many advanced features that make them powerful and superior to other microcontrollers such as…
Bluetooth modules like HC-05 and HC-06 are easy to set-up and quick to use with Arduino IDE, but they have their own limitation like high power consumption and they operate on the old Bluetooth V2.0. Also, recently I got myself a new ESP32 DEV kit, these modules has a punch of features like in-built Wi-Fi and Bluetooth, ample ADC and DAC pins, Audio Support, SD Card Support…
Note: This tutorial was written after Arduino has officially launched its support for ESP32 boards. So if you have followed the old method of using GIT to install the boards then you would have to follow these steps again (highly recommended) if you need support for new libraries. If you are working with ESP32 for first time you do not have to worry about this.

MATLAB is versatile software that can be used for wide variety of applications. In previous tutorials of MATLAB, we have explained how to use MATLAB to control DC motor, Servo motor and Home appliances. Here in this tutorial, we will learn how to use MATLAB for Serial Communication. For the receiving end of serial communication, we are here using Arduino…
Heart Beat rate is most important parameter in monitoring any person’s health. In the modern era of wearable devices, there are lot of devices which can measure heartbeat, blood pressure, footsteps, calories burnt and lot of other things. These devices has pulse sensor inside them to sense the pulse rate. Today, we will also use a pulse sensor with PIC Microcontroller to…
Stepper motors is a brushless DC motor that rotates in discrete steps, and are the best choice for many precision motion control applications. Also, stepper motors are good for positioning, speed control and applications which require high torque at low speed.
In previous tutorials of MATLAB, we have explained that how to use MATLAB to control DC…
Have you ever thought about a speaker which can be controlled by your voice!!! Yes, Amazon Echo is the one of the most popular voice controlled Speaker, but in competition with it Google Home is also getting popular. Voice assistants becoming more popular as we are heading towards an era of AI based systems. You have heard about Google Assistant, Apple Siri and Amazon Alexa…
Interrupts is a mechanism by which an I/O or an instruction can suspend the normal execution of processor and gets itself serviced like it has highest priority. Like for example, a processor doing a normal execution can also continuously monitor for some kind of event or an interrupt to happen. That is when an external interrupt is happened (like from some sensor) then the…
In this tutorial, we will show you how to control DC motor using MATLB and Arduino. If you are new with MATLAB then it is recommend to get started with simple LED blink program with MATLAB.
Creating MATLAB Graphical User Interface for controlling DC Motor
After finishing setup with Arduino for MATLAB, we have to…
I recently purchased the Neo Pixel LED strip and was quite impressed by the way it works. The tiny LED’s have an inbuilt driver IC which helps us to control each LED individually and can produce a wide spectrum of colors. Being a garish person who is obsessed with colours I really loved watching these tiny LED’s changing colors so I decided to build something on my own and…
While Internet of things (IoT), Industry 4.0, Machine to Machine communication etc are getting increasingly popular the need for wireless communication has become incumbent, with more machines/devices to speak with one another on the cloud. Designers use many wireless communication systems like Bluetooth Low Energy (BLE 4.0), Zigbee, ESP43 Wi-Fi Modules, 433MHz RF…
In electronics, Servo motors are mostly used in Robotics Projects because of their accuracy and easy handling. Servo motors are smaller in size and they are very effective and energy efficient. They provide high torque and can be used to lift or push weights according to motors specification. In this tutorial we will learn about Servo Motor and How to interface…
