Debugging Hardware and Software Issues in a Raspberry Pi Pico Model Railway Project

Penguin Tutor via YouTube

Overview

Learn about common hardware and software debugging challenges encountered during a Raspberry Pi Pico model railway point controller project through this 16-minute technical video. Follow along with real-world demonstrations of troubleshooting scenarios including solenoid failures, voltage issues, PCB design challenges, and GPIO expander problems. Explore compatibility considerations between different model railway manufacturers like Hornby and Peco, understand the implications of wireless implementations, and discover the differences between hard and soft I2C implementations. Gain practical insights into electronics prototyping, testing methodologies, and creative debugging approaches like using a debug duck. Benefit from lessons learned and future design considerations that can be applied to your own model railway or electronics projects.
