The $50 robot - Serial cable

[otakis]

hello,
i am from Greece and this is my first robotic project (great tutorial).
sorry for my bad english.

today i was constructing all electronics, but i don't understand the connections of the flat serial ICSP cable (in the female serial connector).

please help me!
thanks

I ask informations for this cable!

[Trumpkin]

what information do you want? (please explain better)

[otakis]

what information do you want? (please explain better)

the connections in the female serial connector (in the circle).
which cable correspond to which pin (10 cables to 9 pins)

Do you have a multimeter?

You can use the diode test to see which pins in the DB9 connecter go to which pins on the pin header connecter.

no, no...
i haven't serial cable...
i must construct this cable

the "cable" in that picture is the programmer. there are diferent ones. the one in the pic is ~$14 but you can get a better one for $30

[Trumpkin]

i think he wants to make the programmer.

good luck with that. didnt work for me

The cable is not a simple rewiring of a connector. It has some electronics inside the big grey part of the DB9 port. It is still possible to make an equivalent of this cable, but it wont be as simple as i think you thought. 

[Trumpkin]

i actually took mine apart once and it didn't seem like it would be that hard to make.

[gamefreak]

just for the record there is actually 10 parts of the programming cable, the 9 pin holes, and the outer rim make up the 10 pins.

thanks all for the responce

Thanks otakis, I was also looking for this   will try first making the programmer, if it fails, then I will have to buy a programmer, which would be probably the AVRISP, but the Arduino is also under consideration, but with the fundamental question: can the Arduino be used to program ATmega** MCU's on the robot instead of on the Arduino board, but like the AVRISP / LPT programmers do?
