Sad Cat Fixer Toy

This instructable is a toy to make a sad cat happy. It is in the shape of a rectangular box with a small hole in the middle. The hole is big enough for the cat to stick its paw inside. In the hole is a servo rotating a toy mouse in a clockwise direction. There are buttons inside at the back of the box that runs the program when they are pressed. Two buttons control the rotation of the servo and make it rotate fully. One button controls a RGB and turns on the RGB when it is pressed. The RGB then flashes red for five seconds, then green for five seconds, and finally blue for five seconds.

• Servo Motor

• Breadboard

• Arduino board

• 3 Buttons

• Toy Mouse

• RGB

• 2 LED's

• Resistors

• Cardboard Box - big enough for a cat to stick its paw inside of it

• Optional: Cat mat

Make sure the hole you cut out is big enough for a cat to stick its paw inside.

Follow the circuit diagram to build your circuit.

Now it's time to program what you have built, go to Arduino and add the following code:

After programming your circuit, find some sort of small toy that can be attached to a servo and it doesn't have to be a mouse. It's best to choose a toy that your cat would like to play with.

Make sure you put something soft under your breadboard and Arduino board to make sure it's secure.

This step is optional, but if you have a cat mat place it in front of your project.

Run your toy multiple times to make sure everything runs smoothly.
