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 ...

[dunk] constructed an easy to use AVR-based USB controller with the ability to drive up to six R/C hobby servos at once. While the USB-powered Atmega8 he used supplies the necessary PWM signaling … ...

For instance, the Serial Servo Raspberry Pi HAT offers multiple powering options, four Serial Servo connectors, four programmable buttons, an on/off switch, and a 1.14” TFT Display for status ...

This project demonstrates the control of multiple servo motors using the Modbus RTU protocol via RS-485 communication. The Arduino acts as a Modbus slave, receiving PWM values from a Modbus master to ...
