>>> Students, teachers, passionate communication discover the first application to control devices FTDI UART with USB connector (Arduino Uno, Mega, Yun, FTDI XBee ...) directly from the development tool APP INVENTOR 2 . (No need for extra Host Shield or Bluetooth. All you need is a Micro USB OTG to USB Adapter.)
>>> USB Bridge for App Inventor 2 allows through a USB OTG cable to achieve a seamless interface between a USB device and the development tool APP INVENTOR 2.
You'll be able to develop your own new applications using the power of app inventor 2 (graphic, sensors, databases ...) and the powers of your devices available (LED RGB, Servo, AX12A, DC Motor...) equipped with a USB UART at 115200 bauds or other speeds.

Use and recycle your old phone using its internal functions instead of using multiple Arduino shield: touch screen display, MP3 player, SD card reader, SMS sending, GPD, GSM,QR Codes, NFC, bluetooth, wifi, various sensors .. .. for your microcontroller based applications. (Arduino Uno, Mega)
If your device is not recognized, please send me the references Vendor ID and Product ID as the following example to the arduino uno: Vendor ID: 0x2341, Product ID: 0x0001
- USB Host mode support on android device and Android 3.1+ are required
- App inventor 2 and arduino must have the same BAUD RATE !!
Example:Control an arduino uno card with otg usb and APP INVENTOR 2
Send and receive datas from Arduino with Serial.println(), Serial.print() , Serial.read() at 57600 baud rate or other ( 300,600,9600....57600,115200..)
(Test OK at 57600 or 115200 bauds with an arduino méga ADK board)
Version Arduino program with Ardublock
