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.
A servo motor is a type of motor that is used to control the precise movement of a device. It typically consists of a DC motor, a control circuit, and a feedback mechanism. The feedback mechanism is used to provide information about the position of the motor shaft to the control circuit, which then adjusts the power to the motor accordingly. This feedback loop…
A GPS tracker is one of the most simple and interesting projects in the field of electronics, and for one of our projects we needed to track the position of a vehicle, so we started looking for circuits on the internet and were very surprised to find out that there were not a lot of modules available online that can do both GSM and GPS at the same time. On top of…
If you are an electronics engineer or a beginner and want to build an obstacle avoidance robot, you need to first learn how an obstacle avoidance system works! which makes this project of ours super important, because in this project we are going to interface a HC-SR04 Ultrasonic Distance Sensor module with ESP32 and we are going to know every little detail about the…
In the last tutorial, we look at the ESP Rainmaker platform and how we can use it with the ESP32 through Arduino IDE. In this part of the tutorial, we will investigate the RainMaker cloud platform a bit deeper and will try to add voice assistant functionality to it. This setup can be used to build IoT based Smart home, Voice controlled…
In an ideal scenario, a battery should have zero internal resistance. But batteries are not made perfect and the electrodes are not 100% conductive, which creates a small resistance within the battery called internal resistance. Practically batteries will always have some internal resistance. On paper, the value of the resistance will appear low around 0.1Ω for…
In this tutorial, we are going to look at the ESP RainMaker. ESP RainMaker is the end-to-end platform for the ESP chips from Experessif. It is designed as a successor to Experessif’s ESP Jumpstart platform. ESP RainMaker enables customers to quickly design, build and deploy AIoT solutions based on enterprise-level cloud computing without…
If you are thinking about building your next project around a 4-digit seven-segment display, you need at least 12 connecting pins to drive all the segments properly, that is most of the pins for a microcontroller like Arduino. The workaround for this problem comes in the form of an IC, and as the title of the project suggests it's called TM1673 LED Drive Control. So…
When you require a dynamic lighting solution, LED strips are a great choice. They may be mounted almost anywhere, available in a variety of colours, and require very little maintenance. Finding another lighting system that offers as much value and style would be challenging. And even this standard is raised to a completely new level by…
Detecting the amount of light in the ambiance is necessary for many areas of our everyday life, and the sensors which can do this are called light sensors, the most primitive light sensor is a humble LDR. But you can find much more advanced types of light sensors being used in automatic lighting systems for smartphones and other smart…
When it comes to adding a display to your next project there are many options to choose from like OLED, 16x2 LCD, Seven Segment, and E-Paper Display. But there exists another type of display that I feel is mostly ignored due to the lack of coverage by enthusiasts and hobbyists on the internet. So in this article, we decided to shed some light on this cheap and easy-…
Fog and Lights is a combination that has the potential to amuse adults and kids alike, so we decided to venture into the realm of ultrasonic mist maker modules and got our hands on one without much trouble. When we first tested a tiny-looking ultrasonic humidifier module, we were intrigued by the capabilities this small module possessed.…
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…
