ArduDroid

ArduDroid is a simple tool to help you control your Arduino Uno (or clone) from your Android phone via the HC-05 Bluetooth serial model. NOTE: Other Bluetooth modules may or may not work. It's both an Android app and an Arduino program which you can download from the developer's website. ArduDroid performs the following functions:

PLEASE RATE: This is a free app and only through your ratings I can determine if it's worth supporting or discontinuing.

1) Control Arduino's digital and PWM pins.

2) Send text commands to Arduino Uno.

3) Receive/Send data from Arduino Uno over Bluetooth serial using the ever popular HC05 Bluetooth over serial module. It may or may not work with other Bluetooth modules.

This app used to be named Andruino but has been changed to ArduDroid to avoid a naming conflict with another app.
