Now, the code from the "Blink" example in the IDE could be uploaded to the Nano board as it should be and the LED started to blink.If the “Port” sub-menu within the “Tools” menu is greyed out, even though your Arduino Nano is plugged into the USB socket (as shown in the image below), then it’s likely that you have a driver installation problem. So I started again, setting the Arduino IDE platform tool menu "Tools" and "Board" to "Arduino Nano w/ATmega328" (in my case) and "Tools" "Serial port" to "/dev/ttyUSB1" (in my case). After connecting it to USB in the /dev folder you should find a file called ttyUSB0 or ttyUSB1 or so. I didn't do it but my Nano started to blink when connected to the USB port so I thought it couldn't be out of order and should work anyhow. Then I found in a german web article that from time to time you have to reinstall the IDE after a system update of the kernel, so that the serial USB interface works again. Of course I had installed the Arduino IDE (apt-get install arduino) but was not able to program the Arduino nano. Also see Good luck.Īs a linux user (Ubuntu / Linux Mint 17) I had difficulties with the cheap Nano with the CH340G chip getting it to work properly - the upload of any code didn't work at all. A bit of a challenge as I don't read Chinese - but the little cloud symbol with a down arrow kind of gave me a clue. It was not at all necessary to install drivers or make them on the Linux machines - but I did install them for the Mac. So, I have Arduino Nano CH340x working on Mac OS (Mojave), Ubuntu 18.04, Elementary Linux (forget version) and openSuSE Leap 42.3 Malachite. I downloaded the IDE from and used that in my openSuSE machine. Comment: Because of the situation with the repos in Tip 1, I did not even try to install the IDE from the openSuSe repos. if you get message "programmer is not responding". Depending on the generation of the CH340 and esp. 'sudo usermod -a -G dialout $USER' Tip 3: In the IDE under tools make you may need to set your "Processor" to ATmega328P (Old Bootloader). Tip 2: do not forget to add the current user to the dialout group. Download instead from site and follow instructions. The repos do not have nice new versions of the IDE. Tip 1: don't use apt get to install Arduino IDE on Ubuntu, Elementary or other Debian/Ubuntu distros. Just a quick comment re Linux installation - year is now 2019 and Arduino IE is version 1.8.8.
