Hi,

I'm quite new to the arduino, hope that someone clarify..
On the Mini I see 8x AD pin (AD0..AD7)

Does the D in "AD" means that this pins can used either as analog input or as digital input/output ?

BR, Dries

Yes and no. You can use them for both analogue and digital but the AD stands for Analogue / Port D. The pins are grouped in ports of 8 bits each and labeled A, B ... and so on.
