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.
India being a sports-loving country loves to watch sports in a group where the whole neighborhood comes and enjoys the sports together, be it cricket or football. But doing so, one of the problems we face is that the scoreboard on the bottom of our television screen becomes very small and hard to read. So, today we are going to build an IoT and Arduino-based IPL…
NodeMCU is a low-cost open-source IoT platform that initially included firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which was based on the ESP-12 module.
If you are getting started with IoT or microcontrollers in general, this development board is a fierce competition to everything that you’ll come…
In the era of Internet of Things (IoT), wireless communication is getting increasingly popular in everyday life. Nowadays, devices can talk to each other over the cloud or local network. When we talk about local wireless communication, we need an RF system module that executes these tasks, we see can find various RF system modules with various configurations like Bluetooth…
Any electronics projects enthusiast has to first familiarize themselves with basic electronic projects. This includes trying to build simple devices and circuits using components like resistors, LEDs, diodes, transistors, etc. This forms a firm foundation in handling electronic components and helps to build complex projects later. Once familiar with the basics, one can move…
Avengers Assemble! Who does not like the Marvel Cinematic Universe? So, today we have a great project for you people that is a Wi-Fi-controlled Ironman mask. These days evolution and adaptation of 3D printed tools have seen a great increment for a plethora of purposes. We brought the use of a cool 3D printed design to make it into an Ironman mask that can be controlled over…
In this DIY tutorial, we are going to build an IoT-based GPS Location tracker using NEO-6M GPS Module. This Location Tracker Board consists of a NodeMCU, OLED Display Module, NEO-6M GPS Module, and 3.7 to 6V booster circuit. Here, we have also created a simple local webserver to display the location details. This webserver contains a link to directly check the location in…
RFID (short for Radio Frequency Identification) tagging is an ID system that uses electromagnetic waves in radio frequency to transfer data. A simple RFID system consists of just two components: the tag itself and a read/write device. The read/write device consists of a Radio Frequency module and an antenna that generates a high-frequency electromagnetic field while the tag…
Pulse Width Modulation (PWM) is a type of analog modulating technique in which the duration or width of the pulse changes in accordance with the time. It is a commonly used technique to produce a continuous pulse signal with a defined frequency and duty cycle. In short, PWM is about changing the width of a pulse while the frequency remains constant.

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…
A Secure Digital (SD) card is used to store information in many electronic devices, especially smartphone and digital cameras. But did you know that you can read and write information on an SD card with the help of a simple 8-bit microcontroller? You heard that right, it's possible to do so, this opens up a bag full of opportunities in embedded systems and design. Since…
Motion detection is a common application for intruder alarms, light switches, and other home and industrial automation applications. And there are several ways to do it. We have already used a PIR sensor for motion detection, it senses the change in ambient infrared energy caused when a warm body enters the monitored area.
In this tutorial, we…
IR remote is one of the simplest, easiest, and cheapest ways to transfer data wirelessly. The range of this device is not that much but that's exactly why it is perfect for simple Home Automation projects, TV Remotes, and others. Because of such a project, I had to interface an IR remote with a PIC microcontroller. My initial objective was to find a library for IR…
