DIY Your Star Wars Mouse Droid With Hidden Display

Differently from the small black droids that you have seen in the Star Wars saga, the mouse droid by Potent Printables acts as a sort of physical messaging app. It’s able to travel to the correct location, then pop open to unveil a scrolling LED sign.

An Arduino Uno along with an Adafruit Motor Shield are used for control, while an HC-05 module enables communication with the system. So you can trigger the side door using a Bluetooth app on your phone. On command, an RC servo pushes it open, and lowers it down using a stepper motor/reel setup.

All you need to accomplish the control of the door and the LED sign:

• Arduino Uno

• Adafruit Motor Shield (v2) for controlling the stepper and servo

• HC-05 bluetooth module for communication

• 3S Lipo for power

• 2x voltage regulators for stepping down the Lipo
