ESP32: Simple web server using micropython.

Setup Micropython for ESP32: ESP32 is a low cost microcontroller that comes with Wi-Fi and Bluetooth connectivity interfaces. We can develop programs for ESP32 using Arduino and ESP-IDF frameworks. We have explained how to develop a simple LED blink program using ESP-IDF in our previous blog https://c2plabs.com/blog/2021/12/31/esp32-led-blink-tutorial-using-esp-idf-freertos-framework/. In addition to these frameworks ESP32 also supports […]

ESP8266 MQTT Client tutorial using PubSubClient library.

MQTT is a messaging protocol widely used in the Internet of Things (IoT) to control and access smart devices over the internet. This tutorial demonstrates how to develop a simple MQTT client for the ESP8266 NodeMCU using the Arduino framework. In this demonstration, we utilize the ESP8266 GPIO 12 connected to a relay to control […]
