The IoT device needs to be coded to communicate with *test.mosquitto.org* using MQTT to send telemetry values with the light sensor reading, and receive commands to control the LED. In this part of ...

This library adapts the mqtt-ai/esp-mcp-over-mqtt ESP-IDF component so it can be used in the Arduino IDE together with the Arduino-ESP32 core. It lets you expose MCP tools and resources over MQTT 5 ...

Makers, developers, and hobbyists who enjoy creating projects using the Arduino platform may be excited to learn that Adafruit has recently announced that their MQTT Arduino Library now supports the ...

The project itself is very simple: getting push notifications via MQTT when a wireless doorbell sounds. But as [Robin Reiter] points out, as the “Hello, world!” program is a time-honored tradition for ...

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...
