I'm new to this whole arduino development things, so please dont punch me for my questions smiley But arduino looks really great, so I want to increase my knowledge and start with a projekt:
I want to create an ecg (electro cardiogram) device, running with battery and sending data via gprs to a webserver:
My basis would be an arduino ( i dont know which, but i think smalles possible (tip which would work? smiley )) with 2 shields:
GPRS Shield V.2 http://www.seeedstudio.com/wiki/GPRS_Shield_V2.0
OLIMEX - SHIELD-EKG-EMG - BOARD,ECG / EMG ARDUINO SHIELD http://at.farnell.com/olimex/shield-ekg-emg/board-ecg-emg-arduino-shield/dp/2144343 http://www.farnell.com/datasheets/1641097.pdf
As battery i would like to use some high capacity mignon/aa rechargeable batteries (4x1,2 Volt with 2700mAh each) .
Do you think this would work? Im not very good in electronic calculations, and I would like to ensure that i dont waste much money for components which wont work together. I also read that some shields cant work together, because the use the same software/hardware serial ports.. But I dont understand the manuals and which ports are when used or how..
Can you maybe help me? :) Thanks a lot!
