Libraries

Install these libs in your $HOME/Arduino/libraries or $HOME/sketchbook/libraries

https://github.com/maniacbug/StandardCplusplus

Quickstart

Connections

The project is designed for an Arduin Mega and 300 pixels of WS2801 arrangd in 15 lines and 20 columns, starting from bottom right. The LED model can easily be replaced by other LED models as long as you replace the Arduin library WS2801 by the library matching your model (WS2812B/SK6812, WS2813, ...)

  1. Connect a HC05 or HC06 Bluetooth device to the pins Serial1 pins of your Arduino Mega.
  2. Connect a LED strip of 300 pixels to the SPI MOSI+SCK pins of your Arduino Mega

Power WS2801 with their nomial voltage (12V) and the Arduino somehow (USB or DC jack), and load the programe hereunder.

Software: Arduino-side

Install the following libraries for Arduino:

Then upload the sequence sketchbook to your Arduino

Software: Smartphone-side

The joystick is emulated on with an Android phone on which you can compile and install the following app Arbalet Saint Jean.

Note for Apple devices

No iOS app is available since iOS is not compatible with Bluetooth SPP. The artwork should work in iOS, though, if you replace the HC05 by a HCI-caapable chip such as RN42 and use some i0S app emulating HCI joystick on the smartphone.
