eto pa isa...
graduating ka na malamang. sana yung subject mo instead na "newbie help please"
pwede naman na "ECG schematic, not working on actual circuit" or something.
don't do it next time. forget about it.
anyways... don't read it from a multimeter. read the blog itself.http://www.swharden.com/blog/category/diy-ecg-home-made-electrocardiogram/
step by step.
other than that. you won't be able to recreate it.
ECG signals ba kailangan mo? or PULSE lang. like "heart rate" magkaiba kasi ang "ECG" at "Heart Rate" Clarify ko lang;
mag iinterface ka ba sa PC or laptop. (kasi mas maingay ang PC than laptop.)
MCU based ba ito or what?...
madami jan sa internet na much better na schematic.
