If you are like me and ordered a cheap arduino nano clone from a chinese website like aliexpress or banggood, chances are that they come with the cheaper CH340 USB to Serial chip. This is a cheap chip that manufacturers exploit to make the clone a lot cheaper. This can also be a downside. For me, being a mac user, I had a real hard time finding drivers etc for it. In the end I found some drivers, which were pretty good and I finally could get a blink sketch uploaded. I now want to share my experience for future buyers so you can get it working a lot faster. If everything is done correctly and there were no errors appearing.

You should be able to restart your arduino IDE and see the port. For my mac it is usually like above in the picture but sometimes it changes. Netflix app for macbook free download. You will also notice that once in a while (maybe 1 time of 3) you will get errors when uploading but you do not have to care, the code will usually upload either way.

I hope this tutorial helped you and remember that the CH340 chip is a bit complicated and it may also be used in other cheap arduino board clones. Thanks for reading and once again, I hope it helped you. As 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. Of course I had installed the Arduino IDE (apt-get install arduino) but was not able to program the Arduino nano. 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.

How do you freeze the top row in excel for mac. Freeze the top row and the first column. To freeze the top row and the first column at the same time, click cell B2. Then, on the View tab, click Freeze Panes. Freeze as many rows or columns as you want. Want to freeze multiple rows and/or columns? You can freeze as many as you want, as long as you always start with the top row and the first column. To freeze multiple rows (starting with row 1), select the row below the last row you want frozen and click Freeze Panes. Actually, you can freeze panes without splitting the screen first. Just click on a cell then click on Window > Freeze panes. This will freeze the cells to the left of and above that cell. To freeze the first row and column, open your Excel spreadsheet. Select cell B2. Then select the Layout tab from the toolbar at the top of the screen. Click on the Freeze Panes button and click on the Freeze Panes option in the popup menu. Now when you scroll, you should still continue to see row 1 and column A.

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. After connecting it to USB in the /dev folder you should find a file called ttyUSB0 or ttyUSB1 or so. In my /dev folder I had found it. 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). 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.

The best USB to Serial drivers for macOS Drivers for CP2102 / CH340 / CH341 / PL2303 Devices. Program your Arduino, ESP8266 within a couple of minutes, control your Cisco, or download your GPS tracker, our drivers enable it. CH340 Drivers for Windows, Mac and Linux The CH340 chip is used by a number of Arduino compatible boards to provide USB connectivity, you may need to install a driver, don’t panic, it’s easier than falling off a log, and much less painful.
