Introducing the production process of a model railway controller that can be remotely operated via smartphone using a Raspberry Pi and Contec I/O board!
Using a Raspberry Pi makes it easy to implement electronics projects linked to the internet. This document explains the process of creating a "Raspberry Pi Model Train Controller" that can be operated from a smartphone's web browser, divided into Part 1 through Part 3. It covers how to turn the model train on and off from the Raspberry Pi, easy programming with Node-RED, noise countermeasures using Contec's highly reliable I/O board, all explained with photos. Additionally, it includes software implementation, operation from the dashboard, usage instructions, and a summary of automatic control for model trains at the end. We encourage you to read it. 【Products Used】 Expansion board to add 8-point/8-point opto-isolated digital input/output to Raspberry Pi - CPI-DIO-0808L *For more details, please refer to the PDF document or feel free to contact us.
