Microbridge is a software stack that allows for communication between an Android mobile phone and an Arduino micro controller using the Android Debug Bridge (ADB) interface. Unlike the official Android Open Accessory Development Kit (ADK), which is a complete software stack on the Android operating system (versions 3.0 and greater), Microbridge works by creating a TCP server on the phone, using the ADB protocol, on a given port, which the Arduino communicates to the phone using. The protocol allows for bi-directional communication between the Android mobile phone and the Arduino. Microbridge requires an Arduino USB Host Shield to properly function.

Using Microbridge with an Arduino and Arduino USB Host Shield allows for actuation of servos, DC motors, and allows for PWM communication, among other uses, through and Android phone.[1]

Android hardware support[edit]

Microbridge is designed to work on unrooted Android phones with software version 1.5 and greater. It is confirmed working on the following phones:
