Real Hardware in Survival

No magic commands. Craft the Laptop, build your circuits, and connect them using in-game resources.

Plug & Play

Compatible with Arduino Uno R3, Uno Q, ESP32, and any Serial board. USB or Wi-Fi with token pairing.

Code as Redstone

Control Redstone with real sensors or activate physical LEDs with in-game events.

Native Multi-Language

The mod automatically detects your region. Available in English and Spanish (with localizations for Spain, Argentina, Mexico, and Peru).

What is SerialCraft? ​

SerialCraft is a mod for Minecraft (Fabric) that breaks the fourth wall, allowing real-time bidirectional communication between the game and external electronic devices.

About the Authorship and Project Philosophy ​

SerialCraft is a project created by Leonardo Aliaga (Instagram: @aliaga1924). It was born with the main purpose of being a learning project, focused on exploring the intersection and synergy between software development (Java modding via Fabric), physical hardware design, and telecommunications (as a student at Universidad Nacional Mayor de San Marcos).

The Role of Artificial Intelligence ​

In the development of SerialCraft, AI tools are employed strategically to optimize time. The project does not rely entirely on AIs to exist. The creation process is meticulous:

  1. First, the architectural structure and programming logic are established through personal reasoning and deep study of the Fabric API and hardware libraries.
  2. Subsequently, AI tools are used to execute more quickly and translate those structured ideas into functional code, accelerating production and allowing focus on creativity and technical innovation.

What can you do with SerialCraft? ​

  • From Minecraft to the Real World: Make an in-game lever turn on a real desk lamp or activate a motor.
  • From the Real World to Minecraft: Use physical buttons, light sensors, or temperature sensors to open doors, trigger traps, or generate Redstone signals within your game.
  • Learning and Prototyping: It is an excellent tool for engineering students, robotics enthusiasts, and hardware hobbyists to test circuit logic in an immersive sandbox environment.

How does it work? ​

The mod uses serial protocols (USB) and TCP sockets (Wi-Fi) to open a direct channel between the game and your hardware.

  1. Input: Your board sends data (e.g., light sensor) -> Minecraft receives it and activates Redstone blocks.
  2. Output: Minecraft detects energy in IO Blocks -> Sends states to the hardware to activate physical actuators.
