ArduinoDroid - Arduino IDE

Write, compile, and upload Arduino sketches directly on your Android device with ArduinoDroid - Arduino IDE, the complete mobile development environment for Arduino, ESP8266, and ESP32 boards. No internet connection or cloud service account needed — everything runs locally on your phone or tablet.

Turn your Android device into a fully functional Arduino IDE. Whether you're prototyping in the field, teaching embedded systems, or iterating on IoT projects, you gain the ability to code and deploy without a computer. ArduinoDroid supports all major Arduino boards including Uno, Nano, Mega, Leonardo, and the full ESP32 family (including ESP32S3 and ESP32C3), plus ESP8266 modules. Upload sketches over USB for direct board connections or wirelessly via WiFi OTA updates on ESP8266 and ESP32 boards.

Develop faster with built-in productivity features designed for mobile screens. Real-time syntax highlighting with customizable themes keeps your code readable and error-free. Code complete suggestions accelerate your typing, while integrated diagnostics catch errors and warnings instantly with one-tap fixes. A responsive file navigator lets you manage multiple sketches effortlessly, and a specialized software keyboard optimizes typing for embedded development. Browse and edit your sketch library directly, with hundreds of example sketches and community libraries already included to jumpstart your projects.

Monitor your board's serial output in real time using the integrated serial monitor — essential for debugging and testing. Connect via USB on devices with host support, or establish WiFi connections for remote monitoring of ESP boards. Cloud flexibility lets you seamlessly sync projects between devices: save sketches to Google Drive or Dropbox, then pick up where you left off on any Android device.

Built for developers who value simplicity and self-reliance. The material design interface feels native to Android, and offline-first architecture means you're never blocked by connectivity. Compilation happens locally without root access, keeping your device secure and your workflow uninterrupted. Advanced features including code complete and real-time diagnostics are available as premium unlocks for serious makers.

ArduinoDroid - Arduino IDE empowers you to prototype, develop, and troubleshoot embedded projects anywhere. Take your Arduino development off the desk and into the real world.
