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 ...

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 MQTT protocol is ideal for this type of application. A practical example of its use is the following: an analog thermometer, connected to Arduino UNO R4 detects the ambient temperature and sends ...

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...
