creating a simple project where two Arduino Uno R3 boards communicate wirelessly using the nRF24L01 modules. Let's create a simple project where two Arduino Uno R3 boards communicate wirelessly using ...

* MQTT (MQ Telemetry Transport): a lightweight protocol that's primarily designed for connecting power-constrained devices over low-bandwidth networks. * For example, a MQTT packet can be as small as ...

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 ...
