Automatic Turtle/Fish Feeder Version 4

thingiverse

This is yet another ingenious design of a fish feeder driven by Arduino. The separate unit consists of an Arduino Uno connected to the feeder, which operates in complete independence. Here are the essential requirements: * A reliable Servo * An efficient Arduino system * Bearings-free construction Print without supports at 10% infill rate Settings for PLA printing material: Extruder temperature: 200 degrees Celsius Bed temperature: 60 degrees Celsius Now, follow these clear and concise instructions: Arduino code implementation: // Speedy Auto Feeder v4 with v6 firmware compatibility #include "Wire.h" int flag = 0; Servo myservo; // define a Servo object to control the servo int pos = 0; // variable for storing servo position void setup() { myservo.attach(9); // connect servo on pin 9 to servo object myservo.write(0); // tell servo to assume initial position in 'pos' } void loop() { // Repeat cycle four times: myservo.write(180); // adjust servo to designated position delay(1000); myservo.write(0); delay(172800000); // pause for two days (172800,000 milliseconds) // delay(5000); // additional five-second waiting time // Repeat cycle again: myservo.write(180); delay(1000); myservo.write(0); delay(172800000); // repeat two-day wait // Add pause before executing final cycle: myservo.write(180); delay(1000); myservo.write(0); delay(86400000); // end the last loop with a single one-day delay
