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.
In this project, we are going to build an audio bug using Arduino and NRF24L01. This audio spy bug is highly customizable and can be easily integrated with other devices and systems. The NRF24L01 module allows transmission over specific channel, ensuring that our transmissions remain private up to a level. This device is perfect for…
In the previous parts(Part 1, Part 2, Part 3) of this project, we investigated different aspects of our smart watch projects and learned to integrate and test each individual part. In this we are going to use what we have learned to create our own smartwatch from scratch, using a combination of hardware and software components. Throughout…
If you are interested in building robots, then it is certain that you need to learn how to control the speed and direction of a DC motor, and in one of our previous tutorials, we did just that using the popular L293D Motor Driver IC and ESP32. However, there is a different IC called DRV8833, which is also a dual drive motor driver solution and is cheaper than the…
Discover how you can build a professional digital multimeter using Arduino that measures up to 24V DC voltage, checks resistance, conducts diode testing, and performs continuity tests. This comprehensive Arduino based multimeter project provides full circuit diagrams, programming code, and even a 3D printed enclosure design.
A…
We at Circuitdigest have worked on a lot of PCB projects, but have consistently faced a challenge during the assembly process. Specifically, when working with SMD components, the use of solder paste is crucial. While SMD stencils are the most efficient method for applying solder paste to a PCB, they can be difficult to obtain,…
Winter is coming and that simply means cold weather with early nights. The perfect way to combat the winter gloom and lighten the mood is to light some candles but burning wax candles inside a closed room will fill up the room with carbon dioxide which can cause health issues. That is why in this article we have decided…
If you are planning on building a robot with DC motors then you will eventually learn that you need to control both the speed and direction of the motor if you want it to move it in a certain direction. And one of the best ways to do it is by using a L293D motor driver IC, because it's cheap, easy to use and with a bit of PWM support it can control both speed and…
Do you remember the old classic 8-bit games? Perhaps you enjoyed your leisure time in front of an early home computer or video game system. They were so nostalgic, and every kid in that era loved them. Now they are replaced with modern high-end graphics and game dynamics. Yet many people still love to play those classic games.…
When it comes to giving your project wireless capabilities, the 433MHz ASK transmitter and receiver is a common choice among engineers, developers, and hobbyists because of its low price, easy to use libraries, and community support. So in this tutorial, we have decided to interface the 433MHZ ASK transmitter and receiver with Arduino and in the process we will let…
Are you tired of having shaky footage ruin your video? Or do you want to make some cinematic, professional-looking shots? Let’s make a cheap and easy-to-make camera slider to solve these problems. In this project, we are going to make a motorized camera slider using Arduino. The entire system is made using off-the-shelf parts such as…
If you are thinking about building yourself a burglar alarm or you are thinking about Automating lights in your room, then you should definitely consider using an HC-SR501 Passive Infrared Sensor or PIR sensor for your project, because as the name suggests a PIR sensor allows you to detect when a person or animal moves in or out from the range of your sensor. And you…
Want to give your project a sense of sound! Then follow along because in this project, we are interfacing a sound sensor to build some interesting projects with it. The KY-038 sound sensor we are using uses a condenser-type microphone to detect sound waves, which gives us a perfect balance of stability and reliability. So in this article, we decided to interface…
