 Bigger Bigger  Smaller Smaller  Reset Reset

Hi guys,

I am completely new to arduino, and I am in the process of making my own single sided board. The parts should be coming tomorrow. Well at least the rest of them, I already have a lot of them. Anyways I realized I have a problem. This uses a serial cable, and both of my computers don't have a com3 port. One computer has a printer port, but I don't know if I can use it. I have an adapter that would work to fit it in there, but when I looked at the compiling software it only has a com3 option. What can I do to make this work?

Any help would be appreciated, and thanks!

Compiling software for the Arduino IDE?

Sorry yeah it is the single sided serial board.

Also the adapter I mentioned is one of these:



And I want to use it to plug into my computer's printer port, since I have no serial port. Would I be able to change an option in the Arduino IDE to make it use the printer port? If not can I get a serial to usb adapter and will it work alright? Thanks man!

"Converting" a parallel port to nine-pins is absolutely positively not going to work.

In the middle right of the board is a six-pin header labeled ICSP.  This can be used to program the processor "directly" rather than through a computer's serial port using the bootloader.  I believe this can be done through a computer's parallel port.  This is something typically done by an experienced Arduino user.  If you're new to Arduino, I suggest getting everything working using a serial port first.

But, even if you use the parallel port + ICSP to program your board, you'll want a serial port so you can debug the program.

Yes.  I've been very pleased with this...

Warning: It ships with a very buggy driver.  Get the latest driver from FTDI (or Microsoft).


But you only need a single serial port not a dual serial port.  Something like this is more appropriate...

or for about 12 bucks you can get one from modern device, usb comes in, ttl happy serial goes out

as far as the com3 thing, i have no clue, i just downloaded the windows binary's and it works fine on com 1 (altho you still need something to convert from the pc's +-12v to the arduino's 0-5v)

The shown adapter is a rather old serial 9 to serial 25 Adapter and NOT an adapter for the parallel port!
