Installing Arduino IDE on Linux Mint 18.3


I have always had a problem installing this piece of software, you can download the archived file from here https://www.arduino.cc/en/Main/Software


Once unarchived you need to run the ./install.sh in a terminal to create the desktop icon. Up to this point everything worked fine, until I plugged the USB cable from the computer to the Arduino board.

Loading up the example blink sketch, then sending it to the UNO resulted in an error message which unfortunately I cannot display because I have resolved the problem.

The problem was the UNO was not recognized on any port, so searching DuckGo I needed to find a BASH command that tells me what is connected to the usb ports. lsusb


which was actually pointless, all it told me was the UNO device
Bus 003 Device 006: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter. I have no idea what to do with that information. So I played around with the Tools/Ports option in the IDE, choosing between /dev0/ttys4 try uploading, /dev/ttys0 try uploading again, same error. These were the only 2 options, until 5mins later, I looked again lo and behold a third option appeared,
/dev/ttyUSB. This has to be it, so tried uploading sketch again and bugger me a new error appeared LoL.



this time access denied. In fact this is something I remember from previous installations so back to DuckGo and find those BASH commands that allows me access.


sudo usermod -a -G dialout <your login name>

sudo chmod a+rw /dev/ttyUSB0


Not sure about the second line (didn't use it)  but all works perfectly now, so expect some Arduino Projects coming up very soon.
