Write with code complete and libraries, compile, upload Arduino or ESP8266/ESP32 sketches over USB or WiFi and monitor your board right from your Android device with ArduinoDroid. No internet connection, no cloud service account is required. Important: The app takes about 500Mb in internal storage as it contains IDE, compiler and uploader for AVR and ESP8266/ESP32. Make sure you have enough free space and it can't be currently installed on sd card because of Android security policy. Features: * onboarding * open/edit Arduino/ESP8266/ESP32 sketches * example sketches and libraries included * code syntax highlighting with themes support * * code complete * * real-time diagnostics (errors and warnings) and fixes * * file navigator * * tiny built-in software keyboard * * compile sketches (no root required) * upload sketches over USB (all ESP8266 boards, all ESP32 boards, Arduino Uno/Uno_r3, Duemilanove, Nano, Mega 2560, Leonardo, Micro/Pro Micro, Pro, Pro Mini, Yun, Esplora, Robot Control, Robot Motor boards are supported, android devices with USB-host support required) and WiFi (OTA for ESP8266/ESP32) * serial monitor * works offline (no internet connection required) * Dropbox support * Google Drive support * material design App blog: https://www.arduinodroid.info Troubleshooting: https://www.arduinodroid.info/p/troubleshooting.html Advanced paid features (marked with *) review: https://www.arduinodroid.info/p/advanced-features.html See also CppDroid app: https://www.cppdroid.info Note: this is NOT an official Arduino team application, but a 3rd-party mobile application with the same functionality developed and supported by an independent developer. © "Arduino" is a trademark of Arduino team.
