A simple interface to GPIO devices with Raspberry Pi
Role in this project:Back-end Developer
Back-end DeveloperContributions:6 reviews, 658 commits, 360 PRs in 6 years 3 months
Contributions summary:Dave primarily focused on improving the codebase and implementing new features for the GPIO Zero library, a Python interface for GPIO devices on the Raspberry Pi. They refactored existing code, refactoring output devices, and implemented a range of new classes, including a class for the `HC-SR04 ultrasonic sensor` and the `RotaryEncoder` input device. Furthermore, the user addressed the potential problems with threading by making the changes in code that would ensure threads worked smoothly across different python versions. They also added code for additional documentation to ensure users could benefit from the updated features.
