Arduino Board: Executes the code for Modbus communication and servo control. Servo Motors (x4): Controlled by the Arduino based on Modbus input. RS-485 Module: Provides a communication interface for ...

In the setup () function we set the pins were the LDR are connected as INPUTs and position the servo motor at 90° then wait for a 2 seconds before the code execution inside the loop (). In the loop () ...

His code listens for serial commands and manipulates the motors accordingly. He wrote a Python script using pyserial which talks to the Arduino.

4. Arduino Code Logic Initialization (setup): The servo motors are attached to their respective pins using the Servo library: servo.attach (6); servo1.attach (9); servo2.attach (10); servo3.attach (11 ...
