Create Microcontrollers
Create Microcontrollers adds a programmable computer block to Create, written in Lua 5.1, that reads and drives machines, redstone and wireless channels.
What it does
A microcontroller is a craftable block that runs a Lua 5.1 program. Programs can be split across several files, with main.lua starting the others, and the code is kept in the block after a power loss or a world reload. Each program gets a thread of its own and a limited number of instructions per run, so a busy loop cannot lag the server.
The block mounts block reads for inventory contents, fluid tanks, energy and blockstate, and it listens to channel outputs as redstone signals from 0 to 15. Power comes from rotation or Forge Energy, and a program can run for a long time on that supply. Two helper blocks extend it: sensors publish values and receivers turn channel signals back into redstone, and a handheld Controller item binds keys, mouse buttons and scroll wheel input to channels.
Installation needs only NeoForge 1.21.1, and the mod runs on client and server, so both sides need it. The code is under the MIT License and is not open source.
Key features
Lua 5.1 programs
The block's own editor provides file tabs, syntax highlighting and find, and programs can be split across multiple files.
Block reads and writes
A program reads inventory, fluid, energy and blockstate data from mounted blocks and writes to them directly.
Wireless channels
Named channels carry numbers, text, booleans and tables over unlimited range, with one program able to drive many receivers.
Sensor inspector
An open sensor shows the live tree of data a mounted block exposes, and clicking a value copies its Lua expression.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Automating contraptions
A program coordinates machines across a base and makes contraptions react to conditions they cannot sense on their own.
Who it’s for: Players who already build with Create and want logic, sensing or networking without leaving its progression. Server owners can run long-lived programs, since code persists through restarts.
Questions
Does Create Microcontrollers need Create installed?
Must the server have the mod if players do?
Are programs kept after a restart?

What the author says
This mod adds a computer block to Create (NeoForge 1.21.1). You power it with rotation or Forge Energy, open it, write a Lua program, and flash it onto the block. The program runs as long as the computer has power. You can use it to automate contraptions, make your machines really smart, or coordinate things across…
