Hi everyone,
I'm trying to build a homemade ECG according to this schematic:
http://makezineblog.files.wordpress.com/2013/03/ecg_draft4.jpg
Question #1: I don't understand how I'm supposed to use the leg as a ground! How does it apply in real life? Where do the cables go? One end is on the leg, where do I put the other end? On the breadboard?
Question #2: I don't have a Go! Link ADC. What microcontroller/microchip could I use as an alternative?
I'm a beginner, but I need some help!
Thanks
