[Juan_Antonio]

Here more examples of ESP32

ESP32. WiFi. WebServer. LED on/off. Static IP. Soft Access Point

Hello friends, I’ll write in this topic about WiFi on ESP32, LED on/off, Static IP, SoftAP,… 0.- Board D1 R32 ESP32. This is a cheap card ($ 5) with the dimensions and shape of the Arduino UNO, but with the ESP32. I used this card in the ESP32 and BLE tutorials. [esp322pin_h] Search images: D1 R32 ESP32 This card has classic Bluetooth, BLE, WiFi, ADC, DAC, and more feature. This card can be programmed with the Arduino IDE. [base64_11]

The codes for ESP32 are similar to ESP8266. ESP32 has better features than ESP8266.

MQTT and IoT are great friends.

ESP32. MQTT. Broker. Publish. Subscribe. ThingSpeak
