FishTimer

thingiverse

I feed my fish every 48 hours, which keeps the aquarium clean and mess-free, as guppies and PlatCats make excellent tank mates. My PlatCat, Scummy, gets frustrated when he doesn't receive his food on time. I struggle to remember if I fed them last night or not. This is a project aimed at creating a timer that can be reset. The timer turns green when the fish are well-fed, yellow when they're getting hungry, and red when it's time to feed them again. To restart the process, simply press the reset button on the Arduino. Here are the print settings: Printer Brand: Printrbot Printer Model: Simple White Rafts: No Supports: No Notes: Print any Arduino case that provides access to the pins. I used an Arduino Leonardo Case designed by pghauff and modified it with a reset button. Now, let's assemble the circuit: 1. Assemble the four-part circuit. 2. Insert the circuit into the Arduino board. 3. Open the schematic file (.SCH) for a clear understanding of the design. 4. Use the Arduino IDE to compile the sketch (.INO). 5. Post-assembly, insert the Arduino into the printed case. To complete the project: 1. Connect the red lead to pin 13 on the Arduino board. 2. Attach the yellow lead to pin 11. 3. Join the green lead to pin 9. 4. Solder and clip the negative leads together. 5. Add a 330ohm resistor to the negatives and plug it into GND, near pin 13. 6. Upload the sketch using the Arduino IDE. 7. Provide power and enjoy your working timer. The idea for this project was born out of desperation and necessity, fueled by my own frustration with remembering when I last fed my fish.
