JARU for ESP32
JARU IDE for ESP32: Lightweight Development Platform
Develop on Windows, test without hardware, and deploy to your ESP32 board from an environment designed for games, graphics, audio, sensors, and interactive IoT projects.
What JARU for ESP32 is
JARU is a development platform that combines the JARU programming language, a lightweight virtual machine, and JARU IDE. It is designed so you can write clear programs, test them in a Windows VM, and then run them on ESP32 devices with integrated tooling.
Why use it on ESP32
JARU is not trying to replace Arduino, MicroPython, or C++ in every case. It is useful when you want a more integrated experience: language, debugging, GPIO simulation, device configuration, and deployment from one tool.
Workflow
From idea to device with less friction.
Simulate
Run code on the Windows VM and use the GPIO simulator to test LEDs, buttons, ADC inputs, signal generators, and WS2812 strips.
Debug
Use breakpoints, step-by-step execution, Watch values, and console output before touching the real board.
Deploy
Flash and configure ESP32 targets from the IDE, including WiFi, MQTT, displays, serial monitor, and storage.
What you can build
- Arcade games with sprites, maps, scrolling, input, sound effects, and music
- Graphical demos with particles, physics, vectors, animation effects, and custom drawing
- ESP32 interfaces for small displays, watches, dashboards, and embedded screens
- LED strip and matrix projects with animation patterns and visual effects
- Sensor and peripheral prototypes using GPIO, I2C, power management, and device drivers
- Connected applications with HTTP, MQTT, WiFi configuration, files, and storage

Horizontal shoot-em-up demos with terrain, waves, bosses, sprites or primitive rendering, sound effects, and music.
Bubble / JaruTetris / SpaceIntruders
Arcade-style projects using sprites, tile maps, input mapping, score systems, and real-time rendering.
PhysicsBalls / PhysicTest
Physics and collision experiments with dynamic, static, and kinematic sprites.
LedStrip / FXTest / VectorBalls
LED matrices, particles, vector balls, and visual animation experiments.
ParticleWatch / SetupTWatchS3 / SensorMAX30102

FAQ
Is JARU an ESP32 IDE?
Yes. JARU IDE is the main development environment for writing, debugging, simulating, configuring, and deploying JARU programs to ESP32 boards.
Is JARU interpreted?
JARU runs on its own compact virtual machine, designed for desktop testing and embedded targets such as ESP32.
Does it replace Arduino or MicroPython?
Not universally. JARU is a different option for projects where an integrated IDE, VM-based workflow, visual debugging, and ESP32 tooling are useful.
Try JARU on ESP32
Install JARU IDE, open the Blink tutorial, and test the same program first on Windows and then on your ESP32 board.
