In this tutorial, we will build a simple yet powerful data logger using the ESP32 microcontroller. The device will: Read temperature data using a sensor (e.g., DS18B20 or DHT11/22). Store the data on an SD card. Provide real-time monitoring via a web server using WebSockets.

This tutorial guides you through building a heart rate sensor project using an ESP32 and a MAX30102 breakout board. The heart rate data is dynamically displayed on a web page hosted locally by the ESP32, enabling real-time updates without the need to refresh the page. Devices connected to the same …

In this project, we’ll build a fun “Tug of War” game using an Arduino, a LED bar graph display, and buttons. The game mimics a classic tug-of-war, where two players compete to press their button rapidly to pull the “rope” (represented by a LED) to their side.

In this tutorial, we will build a web-based fire alarm system using an ESP32 microcontroller, a flame sensor, a smoke sensor, and Arduino Cloud. This project will provide real-time alerts and allow you to monitor fire-related events remotely via a web interface.

In this project, we’ll use the ESP8266 to connect an MQ-135 gas sensor to the Arduino IoT Cloud. This setup will enable you to detect air quality changes and potentially dangerous gas levels, which you can monitor from anywhere in real time through the Arduino Cloud.

In this project, I will show you how to automatically switch between tabs or hide applications on a Windows computer using a Raspberry Pi Pico and a proximity sensor. By detecting the presence of a person in front of the sensor, we will trigger events in a C# application that …

Parking in tight spaces can be challenging, especially with limited visibility. To help avoid collisions with obstacles, this project will show you how to build an Arduino Parking Sensor using an ultrasonic sensor and a buzzer. The ultrasonic sensor detects the distance to an obstacle, and the buzzer produces warning …

Start your DIY gaming experience with this “Arduino Flappy Bird Project with Dot Matrix.” This project merges the timeless appeal of Flappy Bird with the dynamic capabilities of Arduino and a Dot Matrix display. This article includes hardware setup, gameplay mechanics, and of course, the source code.

A solenoid lock is an electric actuator that converts electrical signals to motion. It is commonly found in electronically controlled doors and drawers. Using the solenoid lock with a microcontroller is easy and, if you’re a beginner, this project is just for you.

For enthusiasts and creators working with Raspberry Pi, the joy of bringing an idea to life is often met with the challenge of maintaining a consistent power supply. This is where SunFounder PiPower comes in to save the day, offering uninterrupted power supply (UPS) specifically designed for your Raspberry Pi …
