Data Logger Project Recommendations

[muttleytm]

I need a data logger for two or three analog inputs. The voltage will be from 0 to 5 volts DC, one of the inputs will be mA.

I think a data logging shield will handle the data logging, but, what Arduino boards, etc will I need to couple it with.

The unit will be portable to I will use some sort of 6 volt battery for the sensors. I've never done anything with Arduionos before. Do they have any sort of regulated 5 volt output or is this something I have to add?

TIA

The voltage will be from 0 to 5 volts DC, one of the inputs will be mA.

The Arduino can measure voltages between ground and 5 volts but you should be able to convert from ma to volts. The Arduino can take up to 12 volts as power input and regulates that to 5 volts for the Arduino and other small devices. If you need more power you would need an external regulator.

Thnanks. I did a little looking around and see that I can just use a 250 ohm resister for my purposes to do this.
