Electrical Circuit Data Logger

I want to log the data of a positive lead, and a negative lead and record this data to a file. I want to get the pattern that the light goes on and off. Does anyone know what equipment I need to do this?

I plan on taking this data, and using Adrurino or phigets to recreate the pattern with a LED.

You might be able to use the GPIO pins on the Raspberry Pi if you can get your hands on one.

Although I'm sure you would have a lot of fun with a Raspberry Pi, AFAIK it doesn't have an ADC so unless the voltage on the leads is 3V3, it won't work. I once played around with an Atmel ATMega16 based board and we used its ADC to read analog inputs and do stuff with it like lighting a LED up or down.
I'm not sure if the board was some handcrafted thing, but a lot of parts came from Olimex.
