Serial Monitor not showing anything.


Even though this question looks to be really stupid, I didn't find any working answer anywhere.

I'm doing the tutorials from the Arduino Uno pack and I can't manage to print anything in the Serial Monitor.

Here's what I'm doing :

  • Opening a serial connection (Serial.begin(9600))
  • Trying to print "test" on this serial connection

Here is the code :

void setup(){

void loop(){

And here's what the serial monitor looks like :

You can see that the baud rate is set to 9600 in both.

I'm expecting to see "test" being spammed in the chat box but nothing appears.

In addition, when I'm looking at the console (looks like I can't have both open at the same time ?), this appears in the log :

[12/29/2015, 5:03:07 PM] - [arduino ide - serial monitor] Error in serial port closing: Error: Serialport not open.
[12/29/2015, 5:03:07 PM] - [arduino ide - serial monitor] Serial monitor disconnected from /dev/cu.usbmodem621

Please note that I'm on OSX 10.6.8 and I am using Arduino Studio v0.0.5

Thank your for reading me and I hope somebody's going to be able to help me out :slight_smile:
