I’ve purchased an Arduino Uno board, but it is still on the way (hope it is delivered soon). In the meantime I was reading the docs and trying to setup the environment.
I’m on a Linux Mint machine. I’ve followed the step by step instructions here http://playground.arduino.cc//Linux/Mint.
Got the first step done, everything installed ok, and the IDE opens when I type
arduino in the shell. But I’m stuck trying to add my user to the dialout group. I tried this:
su -c 'usermod -aG dialout <username>' root
And also this:
sudo usermod -a -G dialout <username>
None of them worked. I can’t see the dialout group when I type
groups as the instructions say. I’m however in a number of other groups. Could it be that the group does not exists? Should it have been created after the apt-get install finished? Should I create it manually?
I’m also trying to understand whether or not this step is required for me. The guide says
This allows you to communicate via a serial port
, but the Uno R3 has an USB port. Could it be that this step is only required for older RS232 ports and it is not needed for USB? (BTW my PC has no RS-232 port, only USB ones).
This was supposed to be “easier than going to sleep”. I could try the Windows XP way, but that would get rid of my remaining self-esteem. ]
Thanks in advance.
