Plug & Play

Compatible with Arduino, ESP32, and any Serial board. Simple GUI to connect and configure.

Code as Redstone

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

Native Multi-Language

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

What is SerialCraft? ​

SerialCraft is a mod for Minecraft 1.21.10 (Fabric) that breaks the fourth wall, allowing real-time bidirectional communication between the game and external electronic devices.

Project Philosophy ​

This is a learning project. It was born from the idea of demonstrating that programming logic and physical circuit logic are two sides of the same coin.

Unlike other technical mods, SerialCraft aims to integrate organically into the survival experience:

  • Accessible: You don't need to be an engineer to turn on an LED from Minecraft.
  • Scalable: Useful for teaching basic electronics or creating complex smart home systems controlled from your base.

How does it work? ​

The mod uses the jSerialComm library to open a direct channel between Java and your USB port.

  1. Input: Arduino sends data (e.g., light sensor) -> Minecraft converts it to Redstone signal.
  2. Output: Minecraft sends block states -> Arduino turns on physical actuators.
