Summary of A Simple 2-Way Bluetooth-based Android Controller for Arduino
Andruino is an alpha Android app paired with Arduino firmware to enable two-way Bluetooth control. It allows users to manage digital and PWM pins, send text commands, and receive data via the HC-05 module. The project utilizes a breadboard and jumper wires for prototyping and has been tested on an Arduino Uno and Samsung Galaxy S2 Plus.
Parts used in Andruino:
- Android phone
- Arduino board (Uno or clone)
- HC-05 Bluetooth over serial module
- Breadboard
- Jumper wires
UPDATE: Please note that there no relation between my app and the one with the same name that popped up on Google Play July 3. As for the name ANDRUINO there’s a good chance I might change it to avoid any confusion.
– July 7, 2013: I have completed a comprehensive round of testing and will be uploading the beta, with minor UI updates.

ANDRUINO is a simple tool to help you control your Arduino (or clone) from your Android phone. It’s both an Android app and an Arduino program. Andruino has a simple Android user interface to 1) control Arduino’s digital and PWM pins 2) send text commands to Arduino 3) and receive data from Arduino over Bluetooth serial using the ever popular and really cheap (less than $10 from ebay) HC-05 Bluetooth over serial module or its siblings.
Andruino should work with other Bluetooth modules with some tweaking but I have only tested it with the HC-05. This is an alpha version that’s running fine on my Samsung Galaxy S2 Plus. Please share your experience running Andruino on your phone. Also, while I used Arduino Uno in this prototype, feel free to experiment with other models of Arduino. Please share your experience to help me improve this app.
I have published a guide before on building and programming a circuit with the HC-05 Bluetooth module and Arduino but I will briefly describe again in this guide how to wire the circuit using a breadboard and jumper wires.
