Summary

I made this fish feeder because I was going on A holiday. and I needed to feed my 160 liter tank with about 80 small fish. I feed powdered flakes. The distance between the hopper and the rotating ball is adjustable.

don't be greedy on the infill.

for electronics I used A basic 28BYJ-48 stepper motor, A corresponding stepper motor driver, A arduino uno, and A 9V 1a dc power supply. Note: a 9V 1.5a or 2a will also work.

After assembling it myself I made some adjustments. btw I glued the motor in place bc I didn't want to bother with bolts and nuts.

I'd like to see your makes and remixes.

(NOTE: ask GPT to correct this code bc thingiverse's text editor interferes)
the code i put uploaded to my arduino is:

''''#include Stepper

// Define the number of steps per revolution
const int stepsPerRevolution = 200;

// Define the stepper motor interface
Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11);

void setup() {
// Set the speed of the stepper motor
myStepper.setSpeed(100);
Serial.begin(9600);
}

void loop() {
Serial.println("Moving");

// Move the stepper motor 7500 steps. ↓here↓ you can chenge how much food you give↓
for (int i = 0; i < 7500; i++) {
myStepper.step(1);
delay(2); // Adjust delay as needed
}

// Wait for 24h in milli seconds before the next set of steps
delay(86400000); // 24h
