Introduction

Mac Os Ch340 Driver Win 7

This tutorial will walk you through downloading, installing, and testing the Arduino software (also known as the Arduino IDE - short for Integrated Development Environment). Before you jump to the page for your operating system, make sure you've got all the right equipment.

Required Materials

  • A computer (Windows, Mac, or Linux)
  • An Arduino-compatible microcontroller (anything from this guide should work)
  • A USB A-to-B cable, or another appropriate way to connect your Arduino-compatible microcontroller to your computer (check out this USB buying guide if you're not sure which cable to get).

Windows

This page will show you how to install and test the Arduino software with a Windows operating system (Windows 8, Windows 7, Vista, and XP).

  • Go to the Arduino download page and download the latest version of the Arduino software for Windows.
  • When the download is finished, un-zip it and open up the Arduino folder to confirm that yes, there are indeed some files and sub-folders inside. The file structure is important so don't be moving any files around unless you really know what you're doing.
  • Power up your Arduino by connecting your Arduino board to your computer with a USB cable (or FTDI connector if you're using an Arduino pro). You should see the an LED labed 'ON' light up. (this diagram shows the placement of the power LED on the UNO).

Drivers for Arduino Uno on Windows

Installing the Drivers for the Arduino Uno (from Arduino.cc)

Mac os ch340 driver installer
  • Plug in your board and wait for Windows to begin it's driver installation process
  • After a few moments, the process will fail, despite its best efforts
  • Click on the Start Menu, and open up the Control Panel
  • While in the Control Panel, navigate to System and Security. Next, click on System
  • Once the System window is up, open the Device Manager
  • Look under Ports (COM & LPT). You should see an open port named 'Arduino UNO (COMxx)'. If there is no COM & LPT section, look under 'Other Devices' for 'Unknown Device'
  • Right click on the 'Arduino UNO (COMxx)' or 'Unknown Device' port and choose the 'Update Driver Software' option
  • Next, choose the 'Browse my computer for Driver software' option
  • Finally, navigate to and select the Uno's driver file, named 'ArduinoUNO.inf', located in the 'Drivers' folder of the Arduino Software download (not the 'FTDI USB Drivers' sub-directory). If you cannot see the .inf file, it is probably just hidden. You can select the 'drivers' folder with the 'search sub-folders' option selected instead.
  • Windows will finish up the driver installation from there

For earlier versions of the Arduino boards (e.g. Arduino Duemilanove, Nano, or Diecimila) check out this page for specific directions.

Launch and Blink!

After following the appropriate steps for your software install, we are now ready to test your first program with your Arduino board!

  • Launch the Arduino application
  • If you disconnected your board, plug it back in
  • Open the Blink example sketch by going to: File > Examples > 1.Basics > Blink
  • Select the type of Arduino board you're using: Tools > Board > your board type
  • Select the serial/COM port that your Arduino is attached to: Tools > Port > COMxx
  • If you're not sure which serial device is your Arduino, take a look at the available ports, then unplug your Arduino and look again. The one that disappeared is your Arduino.
  • With your Arduino board connected, and the Blink sketch open, press the 'Upload' button
  • After a second, you should see some LEDs flashing on your Arduino, followed by the message 'Done Uploading' in the status bar of the Blink sketch.
  • If everything worked, the onboard LED on your Arduino should now be blinking! You just programmed your first Arduino!

Troubleshooting

This guide from Arduino has some more details and troubleshooting tips if you get stuck.

Mac

This page will show you how to install and test the Arduino software on a Mac computer running OSX.

  • Go to the Arduino download page and download the latest version of the Arduino software for Mac.
  • When the download is finished, un-zip it and open up the Arduino folder to confirm that yes, there are indeed some files and sub-folders inside. The file structure is important so don't be moving any files around unless you really know what you're doing.
  • Power up your Arduino by connecting your Arduino board to your computer with a USB cable (or FTDI connector if you're using an Arduino pro). You should see the an LED labed 'ON' light up. (this diagram shows the placement of the power LED on the UNO).
  • Move the Arduino application into your Applications folder.

FTDI Drivers

If you have an UNO, Mega2560, or Redboard, you shouldn't need this step, so skip it!

  • For other boards, you will need to install drivers for the FTDI chip on your Arduino.
  • Go to the FTDI website and download the latest version of the drivers.
  • Once you're done downloading, double click the package and follow the instructions from the installer.
  • Restart your computer after installing the drivers.

Launch and Blink!

  • Select the type of Arduino board you're using: Tools > Board > your board type
  • Select the serial port that your Arduino is attached to: Tools > Port > xxxxxx (it'll probably look something like '/dev/tty.usbmodemfd131' or '/dev/tty.usbserial-131' but probably with a different number)
  • If you're not sure which serial device is your Arduino, take a look at the available ports, then unplug your Arduino and look again. The one that disappeared is your Arduino.
  • With your Arduino board connected and the Blink sketch open, press the 'Upload' button
  • After a second, you should see some LEDs flashing on your Arduino, followed by the message 'Done Uploading' in the status bar of the Blink sketch.

Linux

If you are a Linux user, you probably know that there are many different distribution 'flavors' of Linux out there. Unsurprisingly, installing Arduino is slightly different for many of these distributions. Luckily, the Arduino community has done an excellent job of providing instructions for most of the popular versions. Click on the link below that covers your flavor of Linux:

If the above directions did not work for you, or you don't see your distribution, try this catch-all guide.

You can go to the download page and download the latest version of Arduino for Linux (there are 32-bit and 64-bit versions available) when your system is properly set up.
