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.
Have you ever thought of controlling any peripheral from anywhere in the world? Yes the IoT (Internet of things) has made this possible to control any appliance from anywhere and there are many IoT hardware and cloud platform are available to achieve this. We have covered many IoT applications in our previous tutorial. Today we will use Google Firebase cloud to control an…
Today digital meters are replacing analog meters in every sector whether its electricity meter or taxi fare meter. The main reason for that is analog meters have mechanical parts that tend to wear when used for long time and they are not as accurate as digital Meters.
A good example for this is analog speedometer and odometer that is used in old…
When it comes to our loved ones, we always want to keep them healthy and fit. But what will happen if they get ill and forget to take medicine on time? We would be worried, right? At hospitals, there are many patients, and it is difficult to remind every patient to take medicine on time. The traditional ways require human efforts to remind them to take medicines on…
In this tutorial, we will design a system to read the RFID cards using STM32 and RFID Reader. RFID stands for Radio Frequency Identification which reads information by using radio frequencies. RFID’s are used in many authentication systems like elevator parking system, automated toll collection, maintaining patient information in hospitals, automated data collection etc…
Robots have slowly started to crawl into our society to make our life simpler. We can already find the six wheeled food delivery robots from Starship on the roads of UK, smartly navigating among the civilians to reach its destination. Every mobile robot which navigates into the environment should always be aware of its position and orientation with respect to the real world…
As we know that IoT revolution has started from last few years, since then ESP series Wi-Fi modules become very popular among hobbyists and industries. It is a very small chip and can be embedded in small devices. Also, it is cost effective and anyone who knows the basics of Arduino programming can program it and use it in their projects to make it an IoT enabled device.…
In our previous tutorials, we have learned about SPI and I2C communication between two Arduino boards. In this tutorial we will replace one Arduino board with the Blue Pill board that is STM32F103C8 and will communicate with the Arduino board using SPI bus. In this STM32 SPI Example, we will use Arduino UNO as Slave and STM32F103C8 as Master with Two 16X2 LCD display…
Humidity, Temperature and Pressure are three basic parameters to build any Weather Station and to measure environmental conditions. We have previously built a Digital Thermometer web server using NodeMCU and this time we are extending it to Weather Station using ESP12E NodeMCU. In this project, we will measure Humidity, Temperature and Pressure parameters and…
In our previous tutorials, we have learned about SPI and I2C communication between two Arduino boards. In this tutorial we will replace one Arduino board with the Blue Pill board that is STM32F103C8 and will communicate with the Arduino board using I2C bus.
STM32 has more features than Arduino board. So it would be great to learn about communication…
In previous tutorials, we have learned about How to interface GPS module with Computer and how to Track vehicle using GSM and GPS. We also built Vehicle Accident Alert System using Arduino and accelerometer. Here we are again building the same project but this time a MSP430 launchpad and a vibration sensor will be used to detect vehicle accident. So this…
Have you ever thought of getting your device’s location without using any GPS hardware? Sounds interesting!! Yes it is possible to get the location coordinates just using NodeMCU ESP board without any extra hardware. Here we will use ESP12E board to get live co-ordinates of our location. This becomes possible because of Google’s Geolocation API. So let’s see how this…
A Rotary encoder is an input device which helps the user to interact with a system. It looks more like a Radio potentiometer but it outputs a train of pulses which makes its application unique. When the knob of the Encoder is rotated it rotates in form of small steps which helps it to be used for stepper/Servo motor controlling, navigating through a sequence of the…
