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.
When thinking about the best way to control games, drones, robots, etc, the first control mechanism that comes to our mind will be a joystick. Even though the working principle behind these are very basic, they provide excellent control and degree of resolution in many fields. The application of the Joystick is limitless. We can find…
Proximity sensing is a common application for intruder alarms, light switches, and other home and industrial automation applications. There are multiple methods of proximity detection used in the electronics industry. The most common method is to use the PIR sensor, which senses the change in ambient infrared radiation caused by a warm body…
Every engineer and hobbyist nowadays has a workbench for all of their tools and gadgets, and if you're a 3D printing enthusiast, you've probably used the vernier calliper a lot. This emphasizes the significance of precise measurement tools in engineering. After having used many of them throughout our lives, it is now time for us to attempt…
In the last part, Designing Smartwatch using ESP32, we have looked at how to interface the BH1750 ambient light sensor and the MAX30102 Heart rate sensor for our smartwatch project. In this part, we will be looking at how to interface some other types of sensors to our smartwatch. So, here we will be interfacing the HMC5883L/QMC5883L…
In the last part, DIY Smartwatch using ESP32, we have looked at how to make some interesting watch faces for our smartwatch project. In this part, we will be looking at how to interface some sensors to our smartwatch and will be interfacing the BH1750 ambient light sensor and the MAX30102 Heart rate sensor. We will be looking at…
Electrical appliances are all around us, starting from the indispensable charger of your smartphone to heavier appliances like room heaters, air conditioners, washing machines, and whatnot. Given the status quo of a looming global energy crisis, it is vital to have an understanding of the power consumed by these devices. While our monthly electricity bill gives us a…
Wi-fi these days is an incredibly common technology and chances are, you’re reading this article accessing a Wi-fi somewhere near you. But every technology comes with its own set of vulnerabilities and risks, these can easily be exploited to harvest your data. In times like these when data is the new gold, what are some sure shots of making sure that your data…
People may access messages, alerts, health information, and other advanced information easily and quickly using smartwatches. While smartwatches are formally revolutionary as standalone devices, their capabilities essentially increase when used in conjunction with other devices that people carry, such as their smartphones or tablets. In this project, we are going to…
In one of our previous projects, we interfaced SX1278(Ra-02) based LoRa module with Arduino and established communication among them. This was a very simple project and can come in handy for various applications. But what it can't do is establish communication with the internet for modern-day IoT applications. So in this project, we will be using the HPD13A which is…
Adding cameras and vision algorithms to your projects and robots might sound cool but sometimes it becomes expensive in terms of both capital and time. When the task at hand is much simpler like obstacle detection, distance measurement, or depth monitoring, ultrasonic sensors are a great alternate to place your bets on. Not only are these sensors fast…
When we are talking about LoRa, it's been more than 10 years since its first official launch and since that day LoRa is getting increasingly popular day by day. With so many IoT devices available, this low-power long-range wireless communication could fit into a plethora of applications. It is expected that by 2025 we will have 29 Billion devices connected to the…
In our day-to-day life, we use various gadgets such as television, set-top boxes, air conditioners, home theatre, DVD players, and many other remote-operated devices. Different gadgets means maintaining different remote controls which are not only clumsy but also difficult to manage. Universal remote control simplifies our life because it helps us control any IR…
