Features

What You Get

An all-in-one environment I built because I wanted it to exist

🖥️

Complete IDE

Code editor with autocomplete, project explorer, and dockable panels. Everything in one place.

🐛

Visual Debugger

Breakpoints, step-by-step execution, and Watch window. Debug on Windows, then deploy to ESP32.

🎨

📝

JARU Programming Language

Clean syntax, classes, closures, garbage collector. Designed to feel familiar and be practical.

📦

Built-in Modules

GPIO, WiFi, MQTT, I2C, Display, Sprites, Physics, JSON... ready to use.

GPIO Simulator

Simulate hardware from Windows. Includes LEDs, potentiometer, signal generator, oscilloscope, LED strips, switch, push button, and temperature sensor.

Examples

Made with JARU

Games and demos written in JARU, running on the Windows virtual machine.

Sprites, tilemaps, physics, and sound, all from the built-in modules. The same code also runs on an ESP32 board.

JARU for ESP32

A quick route into the ESP32 side of JARU.

Use JARU for small ESP32 apps, graphical interfaces, arcade-style demos, GPIO experiments, MQTT prototypes, and device-focused projects. The detailed ESP32 page explains the workflow and examples without crowding the home page.

Syntax

The Programming Language

Simple syntax, practical features

main.aru
// Variables with type inference
var name = "JARU"
var version = 0.9
var features = ["simple", "fast", "powerful"]

// Functions are first-class
func greet(who)
    return "Hello, " + who + "!"
end

println(greet(name))

// Elegant loops
foreach (var feature in features)
    println("Ok " + feature)
end

About

About This Project

JARU started as a personal project to learn about compilers and virtual machines. It grew into a full IDE because I wanted a comfortable environment to program ESP32 boards.

JARU is an independent project focused on making ESP32 development more visual, integrated, and approachable.

It's free to use. Feel free to explore it and see if it fits your projects.
