How Many Times Can You Upload To Arduino

Ah yes, it is finally time to brand your Arduino practise something! We're going to commencement with the classic hello globe! of electronics, a blinking light.

This lesson will basically become you up and running using the Arduino software and uploading a sketch to the Arduino board. Once you've completed this step nosotros tin can keep to the really heady stuff, which is when we start writing our own sketches!

These instructions generally show Windows software. Except when indicated, the software (should be) identical on all platforms. Linux will exist added one time I figure out how to get it working (yay)

Not much is needed for this lesson, just a USB cable and an Arduino. If you have an older Arduino you may also demand an LED. Whatever LED is fine as long equally it looks sorta like the photo, with a plastic bulb and two legs

Brand sure you've gone through Lesson 0 outset!

	Assembled Arduino lath, preferrably a Diecimila (or whatsoever the latest version is)	Adafruit	$35
	USB Cable. Standard A-B cablevision is required. Whatsoever length is OK.	Adafruit Or any computer supply store	$5
	LED - Optional Virtually any LED is OK, as long as information technology has two wire legs. This part is just required for NG rev c Arduinos (and mayhap other older ones). Diecimila Arduino's take this part 'congenital-in'	Whatsoever electronics supply store	$1

The first thing to exercise is download the Arduino software.

Become to the Arduino Software Download page and grab the right file for your OS. As of Sept 2007 the version is 009 merely you should use whatever is most recent.

The packages are quite large, 30-50 MB then it may take a while to stop

Extract the package onto the Desktop

Windows

Mac OS X

Windows

Mac Os Ten

Double click the Arduino software icon

Windows

Mac Os X

To open up the workspace

I recollect I get the red error text shown because I already have Arduino installed. Either style, it isn't a problem if y'all do or don't see information technology.

The showtime step is to configure the Arduino software for the right chip. Almost all Arduinos use the ATmega168, but there'due south a risk y'all have an ATmega8. Look for the chip on the Arduino that looks similar this:

If the text says ATMEGA8-16P then you lot have an atmega8 chip. If the text says ATMEGA168-20P then yous have an atmega168 chip. If it says "ATMEGA328P-20P" yous have an atmega328p flake

Make sure the right bit is selected (this movie is really old, will be fixed presently). This preference is saved so you only have to set information technology in one case, the plan will remember next time it's run.

Next, its time to configure the Serial Port (also known as the COM Port). Go dorsum to lesson 0 to remind yourself of which port information technology is. On a PC it will probably be something like COM3 or COM4. On a Mac it will be something like tty.usbserial-xxxxx

Windows port selection

Mac port selection

This preference is saved and then you but have to set it once, the program volition remember next time information technology's run.

However, if you have multiple Arduino's, they may exist assigned difference COM ports. And then every time you plug in a new Arduino, double bank check that the correct port is selected.

Sketches are little scripts that yous can transport to the Arduino to tell information technology how to human action. Permit's open up an Example Sketch. Go to the File card -> Sketchbook -> Examples -> Digital -> Blink

The window should now look similar this, with a bunch of text in the formerly empty white space and the tab Blink above it

The first step to getting a Sketch prepare for transfer over to the arduino is to Verify/Compile it. That ways check information technology over for mistakes (sort of like editing) and then translate it into an awarding that is uniform with the Arduino hardware.

Afterward a few seconds, y'all should run across the message Done compiling. in the Status Bar and Binary Sketch Size: in the Notification surface area. This means the sketch was well-written and is fix for uploading to the Arduino board!

To tell the Arduino that information technology should set up itself for a new Sketch upload, you must reset the board. Diecimila Arduino'southward have congenital-in auto-reset capability, so you don't need to do anything. Older Arduinos, such as NG, must be manually reset earlier uploading a sketch. To do that just press the black push button on the correct manus side of the board, shown hither.

Now it'due south fourth dimension to upload. Make sure the Arduino is plugged in, the light-green light is on and the correct Series Port is selected.

If you have an NG Arduino, press the Reset Push now, only before you select the Upload menu item.

Select Upload to I/O Board from the File menu

After a few seconds you should go this screen, with the bulletin Done uploading. in the status bar.

If you get the following error message "avrdude: stk500_getsync(): not in sync: resp=0x00" that means that the Arduino is not responding

So check the following:

• If you lot take a NG Arduino, did you press reset only before selecting Upload carte item?
• Is the right Serial Port selected?
• Is the right driver installed?
• Is the flake inserted into the Arduino properly? (If you lot built your own arduino or have burned the bootloader on yourself)
• Does the chip have the correct bootloader on it? (If yous built your own arduino or accept burned the bootloader on yourself)

If you become the post-obit error message:

It ways y'all dont accept a serial port selected, go dorsum and verify that the correct driver is installed (lesson 0)

and that you accept the right serial port selected in the carte.

If you get the following error Expected signature for ATMEGA

Then y'all have either the incorrect flake selected in the Tools menu or the wrong bootloader burned onto the bit

If you go the following error: can't open up device "COM10": The organization cannot discover the file specified (nether Windows, COM port value may vary)

Information technology ways that you have too many COM ports (perchance you lot've got 9 Arduinos?) You should make sure that the port is numbered as low as possible. You tin can use a program like FTClean to clear out one-time COM ports you aren't using anymore. In one case you've cleaned out the ports, you lot'll have to reinstall the driver again (run into lesson 0).
Alternately, if you're sure that the ports are not used for something else but are left over from other USB devices, you lot can merely change the COM port using the Device Manager. Select the USB device in the Device Manager, right click and select Properties

Then click Avant-garde... and in the next window change the COM port to something like COM4 or COM5. Don't forget to select the new port name in the Arduino software. The lower port names may say (in use) but every bit long equally the other USB devices aren't plugged in, it shouldn't be a trouble. This is a trivial riskier than just using FTClean...

Here is a video showing the timing of the steps described so far.

Some older Arduinos don't have a built in LED, its easy to tell if yours does or not

If you lot have a Diecimila or other Arduino with a built in LED you will see a translucent function as shown

If you have an NG rev C or other Arduino without an LED, the translucent function will non be at that place, and instead yous will see two silver dots

If you don't have an LED, you'll need to add together your own. Whatsoever LED will do, as long every bit it has two legs and kinda looks like the i shown here. LEDs are directional components. That means if you put it in backwards it will not work! To help y'all put the LED in right, the LED manufacturing plant cuts the legs at different lengths. The longer leg goes in the hole marked thirteen and the shorter i goes in the pigsty marked GND

If you accept a Diecimila Arduino, the upload procedure is quite fast, but start the Upload from the software. The board volition automatically reset itself, transfer the sketch and start the sketch. The little translucent LED will start blinking

If you accept an NG arduino, make sure the LED is inserted as indicated before. Here is a video of the entire uploading procedure. Right after I printing the Reset Button I beginning the sketch upload. At that place is a short look while the software prepares to transfer the sketch. And then the two small orange lights blink, indicating the sketch is being transfered. When its done, in that location is a 7 second filibuster until the sketch starts.

If yous don't get a blinking LED, make certain y'all put the part in the right way, in the correct holes, and perhaps endeavor a different LED every bit information technology may be bad.
