IDE: Arduino IDE Version - 2.2.0 Arduino Used: Arduino Mega, Arduino Uno Arduino IDE Version: 2.2.0 Arduino Connection Diagram: The Master Arduino and Slave Arduinos are connected using the RS485 ...

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 ...

The relay module will need 5V from Arduino to power up and will get input from four different digital pins of the Arduino. Now let’s connect the relay module to your home appliance. Take the positive ...

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 ...

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 ...

What do you pick when you want to make something with a nostalgic touch? A radio, of course! Well, the project presented here is about building a compact Arduino FM Radio with the help of an ...

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).

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 ...
