You’ll need 1 part per file, 2 servo motors (MG90 or MG90S), a stepper motor, and a programmable board—plus an optional switch.

Secure the servo motors and stepper motor in their designated mounting locations. Attach these components to the arms:

Insert the screw to firmly secure the assembly, then apply a small amount of adhesive to reinforce the connections.

Attach a pom‑pom to the topmost arm’s mounting hole, or secure a laser using elastic bands.

You’ll find the “fidget_cat.ino” file attached to this project.

For the code:

• The commands `bas.attach` and `haut.attach` define your pin assignments—adjust them according to your wiring configuration.
• The `random` functions set the range of motion; reduce the values for more subtle, less pronounced movements.

I haven’t yet programmed the stepper motor, but you can easily add it if you’re familiar with stepper motor control.

Feel free to reach out if you run into any issues.
