| All components share a common GND, and are powered from the Arduino’s 5V rail. Pin assignments were selected to minimize conflict with internal timers and preserve clean signal timing for both the servo and WS2812 LEDs. | All components share a common GND, and are powered from the Arduino’s 5V rail.

| - | ==== Conclusion ==== | + | ===== Conclusion ===== |
| Working on the PurrGlow Feeder project has been a very interesting and rewarding experience. I spent a lot of time and effort especially on assembling the LED cube, combining five separate matrices into a clean, functional structure was far more difficult than expected. The feeder system itself also posed its own challenges, particularly in calibrating the servo movement and integrating it with the sensor logic. Even though it took a good amount of trial and error, I'm proud that both the animation system and the food dispensing logic now work. The whole project came together nicely, and seeing it function in real life made all the effort worthwhile. | Working on the PurrGlow Feeder project has been a very interesting and rewarding experience.
