  • Arduno Uno.
  • HC-05 Bluetooth serial module.


ArduDroid (formerly 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. ArduDroid 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. This app has been tested and designed for the HC-05 Serial Bluetooth module. Other Bluetooth modules may or may not work. Please see comments section for users who tried other Bluetooth modules with this app.


ArduDroid 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 ArduDroid 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.

ArduDroid is an app that evolved during one of my development projects. Special thanks to engineer Jafar Quttaineh for testing the app and for his invaluable input.

Step 1: How to use ArduDroid

You can use ArduDroid to send commands to Arduino to control a relay to turn electric gadgets on/off, control a robot servo, increase/decrease speed of a motor and reverse direction, dim a light, speed up a fan, and so on.  Furthermore, you can read Arduino pins and sensors then transmit the data back to your android phone.
