ECG Necktie

project goals
to create a circuit-connected necktie
containing a light up heart which can
blink based on a wearer’s input. The
input can either be based on detecting
a subject’s heart-rate or can be based
on bending a flex sensor.

Step 1: Materials and Sensor Set-up

Hey, thanks so much for sharing this, I'm a complete n00b to Arduino and electronics in general, I think I have most of the circuit figured out but I'm still unsure of what "U1A" and "U3A" stand for, could you please clarify that? Also, I could only find "AD623ANZ" (http://www.newark.com/analog-devices/ad623anz/ic-instrument-amp-800khz-110db/dp/59K4402?Ntt=ad623an) and "LMC6484AIN/NOPB" (http://www.newark.com/national-semiconductor/lmc6484ain-nopb/ic-op-amp-1-5mhz-1-3v-%C2%B5s-dip-14/dp/41K2665), would those be ok? Thanks again!

Great! You may want to check out Heart Spark. It also detects your heart rate but has a custom PCB in the heart.

This looks like an AWESOME project. One problem is that I can't read the Arduino code at all. Can you retype that, or make the picture bigger? This looks like a lot of fun!

Thanks!
