fish feeder

thingiverse

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 revolutionconst int stepsPerRevolution = 200;// Define the stepper motor interfaceStepper myStepper(stepsPerRevolution, 8, 9, 10, 11);void setup() {// Set the speed of the stepper motormyStepper.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 stepsdelay(86400000); // 24h}""''
