I tried the same in the classroom with R2007b
No problem with install_arduino, but with
arduino('COM5') I received an error message:
??? Error: File: arduino.m Line: 6 Column: 35
Undefined function or variable 'private'.
Error in ==> StartArd at 10
Is it possible to solve the problem on this version R2007b of Matlab or have I to take time to install R2012a on all classrooms?
