Arduino Bluetooth Controller

AreyouanArduinoenthusiastthatalwayswantedtoremotecontrolyourprojectsviayourAndroidphonebutdidn'thavethetime,thepatienceortheknowledgetobuildanAndroidBluetoothController?ThenARDUINOBLUETOOTHCONTROLLERiswhatyouneed!

ThisandroidapplicationcanestablishaconnectionwithanyArduino/microcontrollerprojectthatinvolvesabluetoothmodule!ItallowstheusertosetaUUIDofhisownbluetoothmoduleinordertoconnecttheandroidapplicationwithhisprojects!!!ThedefaultUUIDthatcomeswiththisapplicationisfortheHC-06WirelessSerial4PinBluetoothRFTransceiverModuleRS232.(IfyouusedefaultUUIDinordertopairtheBTmodulewithyoursmartphoneforthefirsttime,youwillhavetogivea4-digitpassword.Thispasswordis'1234'.)

Theapplicationiscomprisedof4CommandModes:

1.VehicleMode:Bypressingthe"joystick"buttontheusercanremotecontrolavehiclewithspecificgestures.Fortheinterpretationofgesturestocommands,theapplicationusesthebuilt-inaccelerometersensorofthesmartdevice.Thereare8differentgesturesavailable(FRONT,BACK,LEFT,RIGHT,FRONT_LEFT,FRONT_RIGHT,BACK_LEFT,BACK_RIGHT).

Youcansetthesegestureswithyourowncustomcommandsthroughthethemenubutton"SetCommands".
Additionally,thereisaSTOPandanANDROIDbuttonthatcanbeassignedwithcustomcommandsaswell.

***IMPORTANT***Themodeprovidesviathemenuoptionstheoptiontochangetheorientationofaccelerometeraxises(X->Y,Y->X)inordertooperateproperlyinAndroidphoneswithdifferentdefaultorientation.
