Introduction This tutorial will walk you through downloading, installing, and testing the (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. What you will need:. A computer (Windows, Mac, or Linux). An Arduino-compatible microcontroller (anything from should work).
A USB A-to-B cable, or another appropriate way to connect your Arduino-compatible microcontroller to your computer (check out this if you’re not sure which cable to get). An Arduino Uno An A-to-B USB Cable Suggested Reading If you’re new to Arduino in general, you want to check out this tutorial to familiarize yourself with everyone’s favorite microcontroller platform. If you’re ready to get started, click on the link in the column on the left that matches up with your operating system, or you can jump to your operating system here. 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).
Windows 8, 7, Vista, and XP. Go to the Arduino and download the latest version of the Arduino software for Windows.
Arduino Serial Port Buffer Size Mod. Whilst developing the software for our Arduino based Serial Graphic TFT Display a problem with transmitting too much data at once occured. When using our TFT display we expected the controlling program to send a big burst of serial data initially to set various configuration settings on the screen and to display a screenfull of data. I figured it out. When you open a Serial with 9600 baud (Serial.begin(9600);), it's reading/writing at 9600 bytes per second.That means at fastest it can get just under 10 bytes per millisecond. I don't know what the operating speed is, but it seems like the Arduino gets alerted of and reads the first byte before the second one arrives.
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. ( shows the placement of the power LED on the UNO). If you’re running Windows 8, you’ll need to disable driver signing, so go see the Windows 8 section.
If you’re running Windows 7, Vista, or XP, you’ll need to install some drivers, so head to the Windows 7, Vista, and XP section down below. Windows 8 Windows 8 comes with a nice little security ‘feature’ that ‘protects’ you from unsigned driver installation. Some older versions of Arduino Uno come with unsigned drivers, so in order to use your Uno, you’ll have to tell Windows to disable driver signing.
This issue has been addressed in newer releases of the Arduino IDE, but if you run into issues, you can try this fix first. For a nice, step-by-step tutorial with pictures, otherwise the steps are outlined below.
To temporarily disable driver signing:. From the Metro Start Screen, open Settings (move your mouse to the bottom-right-corner of the screen and wait for the pop-out bar to appear, then click the Gear icon).
Click ‘More PC Settings’. Click ‘General’. Scroll down, and click ‘Restart now’ under ‘Advanced startup’. Wait a bit. Click ‘Troubleshoot’. Click ‘Advanced Options’.
Click ‘Windows Startup Settings’. Click Restart. When your computer restarts, select ‘Disable driver signature enforcement‘ from the list. To permanently disable driver signing (recommended, but has some minor security implications):. Go to the metro start screen. Type in “cmd”.
Right click “Command Prompt” and select “Run as Administrator” from the buttons on the bottom of your screen. Type/paste in the following commands: bcdedit -set loadoptions DISABLEINTEGRITYCHECKS bcdedit -set TESTSIGNING ON.
Reboot! Windows 7, Vista, and XP Installing the Drivers for the Arduino Uno (from Arduino.cc). 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 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 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 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. ( 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 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! 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 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. If everything worked, the onboard LED on your Arduino should now be blinking! You just programmed your first Arduino! Troubleshooting If you’re having problems, check out from Arduino. 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.
You can go to the 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. 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.

Hi Lefty, Yes, I followed all the procedures listed in However, the serial port was still unable to be selected. According to this site, it tells 'You can check that the drivers have been installed by opening the Windows Device Mananger (in the Hardware tab of System control panel). Look for a 'USB Serial Port' in the Ports section; that's the Arduino board.
' When I opened the Widows Device Manager as instructed, I could not find a 'USB Serial Port' or the Ports section. What do you think is the problem? I did find an section in the device manager which appears as 'Other Devices' and in this section, USB-Serial Controller was included. However, the problem is this controller could not be installed, at least that was what it said on the properties. Are there any ways, I can update the driver software to solve this problem?
So far, I found no luck. Hi Lefty, Yes, I followed all the procedures listed in However, the serial port was still unable to be selected.

After too many hours and some cups of coffee I found this: which includes (at the bottom of the page) an exe file with the name ch341ser.exe. I executed it and in less of few seconds the issue solved! This company poduces clones with the same chipsets and microcontrolers but with software that runs. So, the 'USB2.0 ser' run out and UNO took a port under 'COM & LPT' section. I have an Arduino Leonardo board that I have been successfully programming, on Windows 7 using IDE 1.6.4. But suddenly it is no longer recognized.
It does not appear as a device in the computer device manager and it does not show up as available on a port, any port! The green 'power' light comes on and the bootloader makes the 'L' light blink after the board is reset, but no communication is possible thru Rx/Tx. I had been using pins 0-5 as outputs to LED's, pins 6-7 as outputs to drive solenoids, pins 8-12 as inputs from switches. Circuit driving the solenoids included diodes for back-emf from the solenoids. It had been 'working', but I needed to make a small tweek and now I can no longer see the board, even with all other stuff stripped off the Leonardo board. What went wrong?
It still runs the program I have loaded, but I cannot get the Rx/Tx lights to blink. Thanks, I downloaded CH341SER.ZIP, created a folder on the desktop, put CH341SER.zip in that folder, unzipped it and ran the Setup file, it took a moment with nothing then it told me it had successfully installed the driver. Surprise, it works great. It shows up as COM3: on my XP machine. Since I am not very good in non English languages here is the final link. It should be the first file below download.
8/5/2015, lots of luck to all. I also run Mint on this machine and it worked just fine so I knew the hardware was OK. Great Find, Thanks Gil. I am having the same problem with the port being greyed out.
I have an arduino mega 2560 I am running a dual boot 64 bit laptop with Ubuntu 15.04 and Windows 8.1. (Port is greyed out in both) I have tried all of the suggestions I can find on the internet and I have so far had no luck. In windows I have tried device manager and if i plug in or unplug the arduino there is no difference in the usb file, so I guess it is not being detected. In Ubuntu I have tried different usb cables I have tried running as root using sudo I have tried adding myself to the dialout group I have tried searching for ls -l /dev/ttyACM0 to give myself permissions for serial out but I get the error No such file or folder I have also tried ls -l /dev/ttyUSB. with the same results as above I have tried dsmeg and the arduino is not found I have tried lsusb and still arduino is not there I have tried arduino 1.0.5 from the ubuntu software center I have tried arduino 1.6.5 as a direct download, un tar'd the file and set it all up in the correct folders.
Serial Port Problem Arduino
But still nothing every other aspect of the IDE seems to work except for being able to upload to the board. The board works ok as I can use it on a desktop PC that has windows 7 and Ubuntu 14.04 I would prefer if I could get it working on the Ubuntu partition as I use that on the most and is much faster than Windows any other ideas on what I can try would be appreciated Thanks Update Turns out the board was at fault! After buying a new mega all worked fine.
