How to Control Raspberry Pi Pico W Digital Pins (Ex. Pi On Board LED) using Modbus TCP/IP Protocol

In this tutorial, we will guide you on how to control the Raspberry Pi Pico W digital pins using the Modbus TCP/IP protocol. We will demonstrate how to turn on and off the Raspberry Pi Pico W onboard LED using Micropython and how to use the Raspberry Pi Pico W as a remote Modbus TCP server/device.

Modbus TCP/IP is a commonly used protocol in industrial automation and control systems. By integrating this protocol with the Raspberry Pi Pico W, we can control and monitor the digital pins remotely, making it ideal for IoT and automation applications.

We will guide you through the process of setting up the Raspberry Pi Pico W as a Modbus TCP server/device. We will also show you how to configure the Micropython environment and write the code to control the digital pins.

By the end of this tutorial, you will have a better understanding of the Modbus TCP/IP protocol and how to use it with the Raspberry Pi Pico W.
