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.
We are all aware of a basic voltmeter, ammeter, and wattmeters, the three basic things you need to measure values on any electronic projects or circuits. Measuring voltage and current with the help of a multimeter can be a good way to start, but one of the biggest problems I face while testing a circuit is, measuring power efficiency. So, today we…
If you are looking for an inexpensive, accurate, easy-to-use temperature sensor, then LM35 is an excellent choice. It has an accuracy of ±¼°C at room temperature and ±¾°C over a full −55°C to 150°C temperature range. It does not require any external trimming, although the main drawback of this sensor is that it outputs data in analog format, making it …
A Hall effect sensor or Hall sensor is a magnetic non-contact sensor that generates an electrical signal proportional to the magnetic field applied to it. Hall effect sensors are widely used in industrial applications like current-sensing, position detection, and contactless switching. They are basically like a small reed switch, and when a magnetic field is around, the…
In this digital age, we come across LCDs all around us from simple calculators to smartphones, computers and television sets, etc. The LCDs use liquid crystals to produce images or texts and are divided into different categories based on different criteria like type of manufacturing, monochrome or colour, and weather Graphical or character LCD. In this tutorial, we…
Raspberry Pi, as we know is a powerful development board that provides a decent amount of computing power in the size of our palm. This combined with the flexibility of python could help us develop many small gadgets that can solve day to day problems. Recently, I needed to build an IVR system using Raspberry Pi, basically, I have to make phone calls and send messages…
There are several soil monitor sensors available that can be easily interfaced with the Arduino or other Embedded modules and can be programmed for different types of projects such as Smart Agriculture Monitoring System. The problem is not having a combined, retrofit module that can easily be used in different projects or applications as needed…
There are multiple Lithium batteries available in the market with larger options in capacity. However, as we all know lithium batteries are need to be charged, discharged, or even stored in a particular manner to extend their life. In this project, we will explore a circuit that will discharge the battery fully and provide the result of how much capacity the battery has.…
Nowadays, sensors play a major role in the safety and security of many different apartments, homes and offices by detecting smoke, fire, or gas and providing an alarm to the concerned person. That is why in today's article we are going to talk about one such sensor which is commonly used in smoke and gas detectors, namely the MQ-2 Combustible Gas and Smoke Sensor. Don't…
When it comes to detecting certain changes in weather conditions, it's pretty unpredictable, and rainfall is one of the most unexpected parameters of weather. So in this article, we decided to Interface the Rain Sensor with an Arduino. The raindrop sensor also known as rain detector sensor is an easy-to-use device that can detect rainfall. It acts as a switch when…
Bluetooth speaker has now become a pretty popular household gadget that we use on a daily basis. So, for today's article, we thought to design and build our own Bluetooth Speaker. To make things a little more interesting, we have added a strip of WS2812B Neo Pixel RGB LEDs that will be used to visualize the music. In order to make the visualization more responsive, we…
If you have ever visited large scale manufacturing companies, the first thing you will notice is that they are all automated. Soft Drink Industries and Chemical industries have to constantly measure and quantify the liquids that they are handling during this automation process, and the most common sensor used to measure the flow of a liquid is a Flow Sensor. By using a flow…
An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is perfect for obstacle avoidance robots, motion detection systems, and proximity sensing applications. Whether you're building your first Arduino project or need a reliable…
