Hi,
I developed an Android application that turns a smartphone into a virtual Bluetooth joystick.
The applications in the robotic field are endless: Home Automation, R/C cars, robotic arms and of course balancing robots
By default, the device transmits data every 200ms
Data format: [STX X Y ETX]
example: [0X02 0X2A 0X30 0X03]
The application is available (for free 8)) here
From you smartphone, access Google Store and search for "Joystick bluetooth Commander"
This demo Arduino sketch will parse data on the serial monitor, and control the pin13 LED
// AndroLED V5
// Arduino test sketch for Joystick BT commander
// LED control for buttons + joystick echo to serial monitor
// ** deprecated, please use AndroTest_V13.ino **
// see reply #181
The Hardware setup is rather straightforward, should you need additional info, just let me know
Enjoy
Edit:
Updated Arduino sketch,
set Baud rate to default 9600
removed softserial
For sketch upload, don't forget to disconnect board TX from Arduino D0
Edit2:
Joystick Bluetooth Commander Version 2.3 is now compatible with Android V3.X and V4.X (Honeycomb, Ice Cream Sandwich, Jelly Bean)
Edit3:
added Serial.println("Bluetooth Commander simulation") in setup() for communication testing purpose
Edit4:
Joystick Bluetooth Commander Version 2.4
Four toggle buttons with visual feedback
Change Log and Arduino sketch modification: please refer to reply #51
Edit5:
Joystick Bluetooth Commander Version 2.5
Change Log: refer to reply #70
Edit6:
Joystick Bluetooth Commander Version 3.0
** major Upgrade **
Joystick Bluetooth Commander is now a full blown two way Bluetooth communication application
Arduino sends back a button status Byte and a user defined data Byte to be displayed on the phone/tablet screen (Bot battery level is a nice candidate)
Communication protocol has changed
Joystick data is now transmitted as an integer = 2 Bytes (Most Significant Byte + Less Significant Byte)
Your V2.5 Arduino sketch needs to be modified for V3.0
See full change Log at reply #74
Updated demo Arduino sketch at reply #90
Edit7:
Fixed link to Balancing robot for dummies
Edit8:
New Arduino demo sketch (V10.1)
Improve decoding algorithm, see reply #98
Edit9:
Joystick Bluetooth Commander Version 3.1
Maintenance release, see reply #100
Edit10:
New Arduino demo sketch (V10.3) << for Artouste
Bug fix, see reply #129
Edit11:
Joystick BT Plus has been released with 6 buttons and 4 data bytes
The actual number of buttons and data fields is adjustable within the Option menu
Fields and buttons labels are fully customizable
See reply #165
Edit11:
Detailed info re Communication Protocol (send and receive)
See reply #154 & #156
Edit12:
Joystick BT Plus (6 buttons, 3 datafields)
and
Total RC Commander (video from IP camera)
are now available see reply #177
More info here
Edit13:
Joystick BT Plus (up to 6 buttons, up to 3 free format datafields) is now
- Joystick bluetooth Commander V4.0 -
and is available on Google Play as a free upgrade.
To allow text datafield, Communication Protocol has changed
Please use and adapt AndroTest_V13.ino demo sketch to your own needs
** deprecated, please use AndroTest_V14.ino **
See reply #181
Edit14:
Communication Protocol for Joystick bluetooth Commander V4.x and Total RC Commander
now fully documented
See reply #188
Edit15:
A video showing tank control using Total RC Commander. has been posted in the Exhibition Section
More info here
Edit16:

For my new project, I am testing a robotic claw using Joystick BT Commander
Edit22:
Good new, classic Bluetooth feature is now available for ESP32
I have ported the basic Arduino demo sketch (AndroTest_V20_POSTED.ino) to this super platform
No wiring, no software setup, nothing !!
just upload to ESP32 and enjoy see reply #914
