The Arduino will control a relay or a servo motor that operates the door mechanism. Python will be used to send commands to the Arduino via a serial port. How It Works Arduino: The Arduino receives ...

DC-Motor with encoder - Arduino sketch: There will be used the PID lib from Brett Beauregard (PID_v2) The lib can be installed from Library Manager. The program code sends the encoder postion to ...

This library allows your Arduino to communicate via Modbus protocol. The Modbus is a master-slave protocol used in industrial automation and can be used in other areas, such as home automation. The ...

Also, the Arduino Modbus PLC with RS232 and Mango M2M HMI is a practical example of how these two embedded platforms can be used to develop a home automation application. Don Wilcher is a passionate ...

This project focuses on PID-position-control experiments with Arduino. The HTML/JavaScript-based GUI enables easy optimization of the parameters. Since there are many articles on the internet about ...
