Welcome to my quick review of an inexpensive 2-channel 5V relay module controlled via RS485 bus utilizing Modbus RTU protocol. As claimed by some online sellers, this easy-to-get Modbus RTU 2-Channel ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

For example, according to Arduino’s website, it is possible to execute Arduino compiled code along with MicroPython one, and have both cores to communicate with one another. It is made possible by the ...

He put it all together on proto-board, although soldering the FM radio module was a bit tricky. The Arduino code is quite simple, and available for download (zip file).

An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

Contains examples of Modbus (RS485) communication with Arduino. In the examples, Arduino Mega is used as the Master, and Arduino Uno is used as the Slaves. The Arduino RS485 Module is used for RS485 ...
