// ============================================================================================ /* Connect the Bluetooth module GND and 5V and to pin 0 and 1 or 6 and 7 as noted in the comment of the digital pin assignment. When connected to pin 0 and 1 two digital ports and the SoftwareSerial library are saved. Also the Bluetooth subroutine can be omitted. This ommision is accomplished bij commenting out the #define BLUETOOTHMOD with two slashes // A disadvantage of connecting to pin 0 & 1 is that upload to the Arduino when the Bluetooth module is connected is not possible because the module inteferes the upload.
