This project is a monster in a box for Halloween. It describes building the crate from wood salvaged from palletts, and the code to randomly open the box.
The motors were from power drills. The main door motor drives an offset disc, like a cam, that bumps the door open anot an inch. By controlling the door, we can open for a peek or bounce the lid to get attention.
An ultrasonic fog transducer from Amazon is also inside the box to add fog effects.
Contains images and ideas for the crate construction
Contains the schematic files for the fan and LED MOSFET controller.
Just contains random notes used while making the box
Contains the sound files and editing information. It also contains the DFPlayer notes.
This is the code that operates a servo to drop an egg. EggDrop is separate from the monster box, but basically it drops a plastic egg on command.
Code to test the H-Bridges
Contains the Arduino source code for the lid mechanism.
Code to sweep the servo 0-180 degrees.
Code used to calibrate the PWM endpoints for servo.h
Code to make the dragon's tail sweep back and forth
