This sample project was built for the IoT and Edge AI Project Contest 2024. More details can be found on our contest page.
The main objective of this project is to monitor the crowd inside specific premises that have entry and exit pathways. This project integrates Arduino Cloud, enabling easy remote monitoring. Let's discuss this…
Shark Tank India - the show which has inspired many Indians to start their own enteprenual journey displayed a company called as torch it. This company is making electronic devices to help the visually impaired.
One such device of this company that caught our eyes was saarthi - a device that will help…
If you're up for a challenge, you could create your own Tetris game using an Arduino and an OLED display from scratch. Don't worry if the idea of making your own Tetris game from scratch using an Arduino and an OLED display sounds intimidating. I'm here to help you every step of the way!
To start,…
A 4x4 membrane keypad is a compact and a cost-effective input device that is commonly used in a variety of electronics projects. It consists of 16 buttons arranged in a 4x4 grid and is covered with a flexible membrane that protects the buttons and ensures their durability. In this blog, we'll go over how to interface a 4x4 membrane keypad…
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…
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.

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…
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…
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…
