Arduino UNO Q Explanation: Hybrid Board With Linux Computer + Microcontroller Explained for Those Curious About It

Arduino UNO Q Explanation: Hybrid Board With Linux Computer + Microcontroller Explained for Those Curious About It Meta description: Arduino's new UNO Q board is a departure from the usual Arduino board, combining a full Linux computer and a real-time microcontroller on a single board, blurring the lines between an "Arduino project" and a "Raspberry Pi project". Introduction Arduino has released one of their most exciting boards in years, the new UNO Q which aims to bring a full Linux computer and a real-time based microcontroller onto a single board, blending the distinction between "Arduino project" and "Raspberry Pi project". What Makes the UNO Q Different Arduino boards have always been microcontrollers, which is excellent for real-time based hardware projects, but don't offer much in terms of an operating system and processing power for anything more involved than basic logic. The UNO Q board changes this by combining two different p...

ESP32 Web Server | Display DHT22 Temperature & Humidity in Your Browser

ESP32 Web Server: Display DHT22 Temperature & Humidity in Your Browser Meta description: Turn your ESP32 into a local web server that displays live DHT22 temperature and humidity readings in any browser on your network — full code included. Introduction If you've already wired up a DHT22 sensor to your ESP32 (see our ESP32 DHT22 tutorial), the next logical step is getting rid of the Serial Monitor and viewing your readings on an actual web page — from your phone, laptop, or any device on your network. In this tutorial, you'll turn your ESP32 into a self-hosted web server that displays live temperature and humidity data from the DHT22 sensor directly in your browser. What This Project Does The ESP32 connects to your Wi-Fi network, hosts a simple web page, and refreshes temperature and humidity readings from the DHT22 sensor automatically. No inte...

ESP32 DHT22 Temperature & Humidity Sensor Tutorial

ESP32 DHT22 Temperature & Humidity Sensor Tutorial (With Code & Wiring Diagram) Meta description: Learn how to connect a DHT22 sensor to an ESP32 and read temperature and humidity data with this complete wiring diagram, code, and troubleshooting guide. Introduction The DHT22 is one of the most popular sensors for measuring temperature and humidity in DIY electronics and IoT projects. Paired with an ESP32 — a microcontroller with built-in Wi-Fi and Bluetooth — it's a great starting point for weather stations, home automation systems, or any project that needs environmental data. This guide walks through wiring the DHT22 to an ESP32, writing the code to read sensor data, and displaying temperature and humidity readings on the Serial Monitor. What This Project Does You'll build a simple circuit where the ESP32 reads temperature (in Celsius and F...
