A simple workout timer that can run classic workout timers such as count up, count down, 40/20 and tabata styles. This project is meant as a challenge to solve a few design problems:
- Building intuitive and easy to use menus on a limited space 16x2 LCD screen
- Reliable rotary encoder input with multiple "gestures" such as double click and long press
- Reusable encoder and button debouncer implementation
- Object oriented, clean approach to Arduino implementation, especially for LCD menus
- Battery operated and easily rechargeable device
Current status: Prototype in progress
- Class based object oriented architecture
- Interrupt pin based stable encoder reading
- Button debouncer with quick feedback (50ms)
- Simple, object oriented LCD menu system
- Large digit timer implementation
- Rechargeable battery integration
- 3D printed case
