Here are provided several Arduino code examples to be used with several sensors and bluetooth connected to the Arduino-Uno board.

The only library needed is for the Sonar sensor: NewPing the library can be installed from: https://bitbucket.org/teckel12/arduino-new-ping/downloads/

The Arduino sensor files have two modes for using the monitor;
one mode for visualisation on the IDE monitor (Serial.print) and one mode to be used for processing (Serial.write).

Following are the connections for the sensors and bluetooth:
