심전도 신호 생성기(ECG Signal Generator) 제작

이형철 2015-03-27 (금) 10:20 10164 1

웹 아카이브(2016-10-16 기록)에서 복원한 글입니다. 일부 이미지나 첨부파일이 빠져 있을 수 있습니다.

Arduino와 쓰다 버린 전극, 저항, 캐패시터, 이번에 구입한 케이스를 이용해

심전도 생성기를 만들었습니다.

회로도

아두이노 소스코드 (timeone 라이브러리 필요)

#include "TimerOne.h"

const float freq = 7812.5;

const byte pin = 9; // PWM DAC
