Arduino Bluetooth Wiring Diagram on Due Boards
Arduino Due has 4 serial communication Rx Tx, where for pinout position and size dimension is almost same as Arduino Mega, but there is a difference for DAC pin, where for Arduino Mega, there is no port DAC, for detail you can check Arduino Mega pinout and Arduino Due pinout on our other articles.
In designing Arduino Bluetooth using Due board, we can use the four Rx Tx serial communication ports freely, but we recommend to use serial 1, 2 and 3 serial communications ports. Because for serial communication port 0 used by Arduino Due to communicate with computer upon uploading the program from Arduino IDE software.
Wiring Arduino Bluetooth diagram on Due board, in this experiment we use serial communication port 3. Wiring Arduino Bluetooth diagram as shown below.
