Arduino Uno x Bluetooth Controller


Hello, i would like to know if it is possible to combine the arduino uno and the bluetooth controller together to make a project, i realised that the mbot is made up of an arduino uno but when i tried to code the arduino uno r3 board with the bluetooth controller it gave me an error,

(Arduino: 1.8.16 (Windows Store (Windows 10), Board: “Arduino Uno”

C:\Users\hp\AppData\Local\Temp\ccVn673t.ltrans0.ltrans.o: In function `global constructors keyed to 65535_0_sketch_nov05a.ino.cpp.o.5874’:

:(.text.startup+0xfa): undefined reference to `mePort’

:(.text.startup+0x102): undefined reference to `mePort’

collect2.exe: error: ld returned 1 exit status

exit status 1

Error compiling for board Arduino Uno)

so im hoping for you to help me fix that

Thank you,



and this is the code
