I’m brand new to Arduino and followed the ‘Getting Started w/ Arduino on Mac OS X’ guide to set everything up, but I ran into some trouble when I had to choose my Serial Port.
The guide says to use a port with /dev/tty.usbmodem in it, but when I connect the board to my computer, no /dev/tty ports appear (not even for Bluetooth). I selected the only non-Bluetooth port that appeared, /dev/cu.usbmodem1421 and everything seems to work fine (I’m able to upload sketches).
Can anybody explain why my /dev/tty ports aren’t appearing and whether or not it matters?
Computer: 2012 MacBook Air running OSX 10.10.5 Yosemite
Board: Arduino Uno R3
IDE Version: 1.6.7
See screenshot for available ports.
