DIGITAL PINs AND ANALOG PINs ON A ROMEO BOARD
nestor 2012-02-14 10:28:01 4738 Views4 Replies I have bought a Romeo board and I will receive it soon. Later, seen some pictures I notice that digital pins have the power pins in "GND"-"VCC"-"Signal" order that is the order that use all sensors I have. But at the analog ones, the order is "5V"-"GND"-"Signal".
At Arduino One board, I usually use analog pins to conect digital sensors but if Romeo has the last order I will haver to use anogher kind of wires to conect correctly dye power.
My question is: Is there any reason for this "5V"-"GND"-"Signal" pins order at analog signals?

Thank you very much

2012-03-02 00:32:20 Hi,
optionally you could just make a minor modification to your cables...
just use the tip of a jumper cable pin. or the tip of a small paper clip to carefully bend upwards the plastic peg holding in the metal female pin. then carefully pull out the wire. repeat the step for the second wire you want to swap. then insert the wires in the order you want them. carefully push down the plastic pegs to avoid having the female pins fall out.
please take a look at the photo sequence below Hector

Yes, it will be easy using a wire with 3 female pin connector to 3 separated pins

nestor 2012-02-14 19:50:32 The original idea of the analog pin order is to let it be compatible with Sharp sensor.
It is not difficult to swap the pins of digital wire though. R2D2C3PO
