Schrödinger’s cat

For the assignment to create something that mimics human or animal behavior using motors, I created a cat scratching inside the box.

Below is a video that describes the concept of Schrodinger’s cat in a delightful way.

The code is very simple. I am using a 5V motor and a transistor, so all I had to do was to pass on high voltage for 300 milliseconds then rest for 1 second in a loop.

void setup() {
  // put your setup code here, to run once:
  pinMode(9, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  //digitalWrite(9, HIGH);
  analogWrite(9, 255);
  delay(300);
  analogWrite(9, 0);
  delay(1000);
}
