How To Upload Code To An Arduino

Arduino Howto

This page is obsolete. You should instead see the Windows Howto or the Mac OS 10 howto (both in the Arduino guide).

These are the steps y'all demand to follow in social club to be upwardly and running:

Become an Arduino board
Download the Arduino environs
Install the USB drivers
Connect the board
Upload a program

one | Get an Arduino board

The Arduino i/o board is a simple circuit featuring the ATmega8 processor from Atmel. The board is composed of a printed excursion board (PCB) and electronic parts.

There are a few ways to go an Arduino lath:

buy a fix made lath. See how you can buy a board or but the PCB.
- European distributor
- US benefactor
build your own board. If yous want you tin can build your own PCB just by downloading the CAD files from the Hardware folio. Excerpt the .brd file and send it to a PCB manufacturer. Be enlightened that manufacturing a unmarried pcb will be very expensive. It's better to assemble with other people and brand xx or 30 at a time. Since you get the full CAD files you lot can make your own customised version of Arduino. if you make modifications or fix bugs delight send usa your changes!
- buy parts. purchase the parts from any electronics store. The Serial version in particular has been designed to utilise the most basic parts that can exist found anywhere in the world. The USB version on the other hand requires some advanced soldering skills because of the FTDI chip that is an smd role. Here is a list of parts for the serial board.
- assemble the board. We put together a stride by step guide on how to build an arduino board. Newbies: never soldered before? afraid of trashing thousands of boards before getting one properly soldered? fear non :) learn to principal the fine art of soldering.
- program the bootloader. In order for the development surround to be able to plan the flake, this has to be programmed with a piece of code called bootloader. See the bootloader page on how to program it on your bit.

2 | Download the Arduino environs

To program the Arduino board yous need the Arduino environment.

Download Arduino: From the software page?.

Linux note: For aid getting the Arduino IDE running on Debian, please come across the FAQ ("How can I run the Arduino IDE under Linux?").

Mac Bone Ten note: Afterward downloading the IDE, run the macosx_setup.command. It corrects permission on a few files for use with the series port and will prompt you for your password. You may need to reboot after running this script.

For more data, see the guide to the Arduino environment.

three | Install the USB drivers

If you lot are using a USB Arduino, you will need to install the drivers for the FTDI fleck on the board. These can exist institute in the drivers directory of the Arduino distribution.

On Windows, you volition demand to unzip FTDI USB Drivers.zip. So, when y'all plug in the Arduino board, signal the Windows Add together Hardware wizard to the FTDI USB Drivers directory.

On the Mac, mount the FTDIUSBSerialDriver_v2_1_6.dmg (on PPC machines) or the FTDIUSBSerialDriver_v2_2_6_Intel.dmg (on Intel machines) deejay epitome and run the included FTDIUSBSerialDriver.pkg.

The latest version of the drivers can be plant on the FTDI website.

4 | Connect the board

If you're using a serial board, power the board with an external ability supply (6 to 25 volts DC, with the core of the connector positive). Connect the board to a serial port on your figurer.

On the USB boards, the ability source is selected by the jumper between the USB and power plugs. To ability the lath from the USB port (good for controlling low ability devices like LEDs), identify the jumper on the two pins closest to the USB plug. To ability the board from an external ability supply (needed for motors and other high current devices), place the jumper on the two pins closest to the power plug. Either way, connect the board to a USB port on your computer. On Windows, the Add New Hardware wizard will open; tell it you want to specify the location to search for drivers and betoken to the binder containing the USB drivers yous unzipped in the previous step.

The power LED should go along.

v | Upload a plan

Open the LED glimmer example sketch: File > Sketchbook > Examples > led_blink.

Hither's what the lawmaking for the LED blink example looks like.

Select the serial device of the Arduino board from the Tools | Serial Port carte du jour. On Windows, this should exist COM1 or COM2 for a series Arduino board, or COM3 , COM4 , or COM5 for a USB board. On the Mac, this should exist something like /dev/cu.usbserial-1B1 for a USB board, or something similar /dev/cu.USA19QW1b1P1.one if using a Keyspan adapter with a serial board (other USB-to-serial adapters use different names).

Push the reset push button on the board and so click the Upload button in the IDE. Expect a few seconds. If successful, the message "Done uploading." will appear in the status bar.

If the Arduino board doesn't show up in the Tools | Series Port bill of fare, or you get an error while uploading, please come across the FAQ for troubleshooting suggestions.

A few seconds after the upload finishes, you should see the amber (yellowish) LED on the board start to glimmer.
