Machine learning (ML) isn’t just for powerful computers anymore. With TensorFlow Lite for Microcontrollers (TFLM), we can run tiny ML models on low-power devices like the ESP32, enabling real-time intelligence at the edge—no cloud needed!

Today, I’m sharing one of my favorite ESP32 projects — a GPS-powered weather station. It’s perfect if you’ve got an ESP32 lying around, a little 1.8" ST7735 TFT screen, and a NEO-6M GPS module. We’ll use your real-time coordinates to fetch live weather data from the free Open-Meteo API, then …

Introduction Ever wanted to measure temperature without actually touching anything? Meet the MLX90614, a cool little infrared sensor that lets you do just that! Whether you're building a DIY thermometer, automating your home, or monitoring industrial equipment, this sensor has got you covered. We have already covered how to use …

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 …
