ESP32 creative coding environment

XOBIT lets a microcontroller become a live, scriptable object.

By Mads Hobye

Write small scripts in the browser, run them on an ESP32, control LEDs and pins, build a live UI, connect over USB or MQTT, and let the AI assistant help shape code and documentation around the project you are making.

  • Code, upload, stop, inspect logs, and recover sketches from the board.
  • Keep projects as revisions with code, chat, specification, and circuit notes together.
  • Drive LED strips, pins, sensors, environment-aware behavior, browser controls, online data, and Home Assistant entities.

Getting Started

Early maturing system

XOBIT is already quite stable, but the firmware is under rapid development. Expect to find bugs sometimes, and expect to update the board firmware as the system matures.

This is still alpha-stage software: use it for experiments and prototypes, keep physical access to the board, and make backups before the work matters.

Built-in Capabilities

Code the board, shape the project, and keep live controls, circuit notes, online connection, AI context, Home Assistant, and firmware updates in one browser workspace.

terminal Live board coding

Write scripts, upload, stop, inspect logs, and recover the running sketch from the board.

 folder_open Local-first projects

Keep revisions, code, chat, specification, circuit notes, and exportable project JSON together.

 usb USB and online control

Start over USB with Web Serial, then continue online with MQTT on WiFi.

 auto_awesome AI-assisted making

Use chat to draft scripts and keep specification context near each project revision.

 tune Live project UI

Expose toggles, sliders, buttons, values, and graphs directly from the running sketch.

 schema Circuit workspace

Track parts, pins, power, wiring notes, assumptions, and generated diagrams beside the code.

 home_iot_device Home Assistant bridge

Expose values, buttons, sliders, switches, and prototype state to Home Assistant.

 system_update_alt OTA firmware updates

Update firmware from the browser with SafeBoot recovery for safer experiments.

Guide Overview

Start with scripting, then choose the guide for the thing you want your object to do.

codeScript language

Variables, functions, arrays, loops, sketch structure, and XOBIT-specific syntax notes.

 terminalSketch basics

Printing, timing, random values, heap checks, and script error helpers.

 memoryPins and actuators

Digital pins, analog input, touch, PWM, servos, fans, and simple physical outputs.

 wavesMath and motion

Scaling helpers, trigonometry, and noise for animation and sensor behavior.

 scheduleLocal time

Synced clock values, local date parts, and timezone-aware timing.

 wb_sunnySun location

Sun position, daylight brightness, and color temperature for place-aware sketches.

 flareLED strips

NeoPixel-style LED setup, RGB/HSV pixels, brightness, palettes, and frame output.

 tuneBrowser UI

Declare live controls, consume UI events, and update values from the running sketch.

 home_iot_deviceHome Assistant

Expose script-defined entities and consume Home Assistant events.

 psychologyUse your own LLM

Give ChatGPT or another model the XOBIT Wrench context URL and ask for a script.

 shield_lockSecurity model
