Iron Man is a fictional comic book character published by Marvel Comics. His true identity is that of businessman and billionaire Tony Stark, who uses high-tech armor in the fight against crime.

Material

  • Arduino Uno
  • 4-channel relay board
  • Ultrasonic module
  • 330 ohm resistor
  • Modulo mini MP3 player
  • Cable p2

Steps

The purpose of this project is to bring an Iron Man doll to life. We use an Ardudino Uno to control everything. When programming, we use the MP3 DFPlayer library and call the function random () to make the choices of the Iron Man audio files.

The audio was taken from Tony Stark's pessimistic films, and were renamed with numbers (001, 002, 003) to be performed by the MP3 module. Link of some auddio files: https://github.com/Sandromesquita/audioIronMan

When a person approaches (about 1.3m), the ultrasonic module identifies and commands the Arduino to call a BURF command (MP3 play command).

EXPANDED TECHNICAL DETAILS

Wearable Prop-Tech Animatronics

This project (distinct from our previous builds) focuses on an "Integrated Suit Hub" to control multiple Ironman-themed effects from a single Arduino.

  • Distributed Control: A central Arduino Nano manages the "Repulsor" light in the glove (using a 1W LED and a MOSFET) and the "Helmet Actuation" (using micro servos).
  • Sound Injection: Includes a DFPlayer Mini to provide high-fidelity "Armor Power-up" and "Servo Whirring" sound effects synchronized with the physical movements.

Power Management

  • Wearable Battery Hub: Optimized for 7.4V LiPo batteries with a high-current 5V buck converter to ensure the servos and the Arc Reactor (NeoPixel ring) don't flicker during heavy movement sequences.
