External LED via Wi-Fi | ESP32 Mini Guide
Tap a button on your phone and watch an LED light up across the room. This External LED via Wi-Fi turns an ESP32 into a tiny web server that hosts a page with ON/OFF buttons.
ESP32 NTP Time Synchronization with LCD Display
In today’s connected world, accurate time synchronization is important for many applications. For example, the ESP32 NTP Time Synchronization with LCD Display project combines two essential features: NTP (Network Time Protocol) synchronization and real-time data display on an LCD screen. Because the ESP32 can connect to internet servers for NTP, it ensures reliable timekeeping. Additionally,…
ESP32 DHT Server: Monitoring Temperature and Humidity
The “ESP32 DHT Server: Monitoring Temperature and Humidity” project uses an ESP32 microcontroller and a DHT11 sensor to track environmental data. For example, the ESP32 connects to a Wi-Fi network and hosts a simple web page. As a result, users can see real-time temperature and humidity readings from any device on the same network. In…
