ссылку на пульсомер, ссылку на код, версия ардуино иде.

как вариант,  код написан для старой версии ардуино иде. 

Blink запускается?

У меня Arduino nano

Я не знаю что это ><
​Я новичек

Этот код работает?

void setup() {
   pinMode(13, OUTPUT);
}
void loop() {
  digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);              // wait for a second
  digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);              // wait for a second
}

Вы очень удачно ответили о версии среды разработки - nano.... улыбнуло

на картинке с гитхаба отчетливо видно, что IDE ардуинки 1.0.6

https://github.com/WorldFamousElectronics/PulseSensor_Amped_Arduino/blob/master/pics/ScreenCapArduino.png

Т.е. в среде 1.6.8 - доступной сейчас для скачивания код компилироваться не будет.

Или ставьте старую среду или вдумчиво вникая в код библиотеки осчастливте нас новой версией библиотек для пульсомера с учетом современной версии.

Удачи.

Да работает. Я разобрался немного, нашел новый код, вроде бы показывает кое как пульс и мне теперь нужно свой экранчик подключить еще к плате. У экрана порты GND VDD SCK SDA RES DS CS . К каким портам на плате чтоб соответствовало коду нужно будет подключить можешь подсказать?

Я разобрался немного, нашел новый код, вроде бы показывает кое как пульс и мне теперь нужно свой экранчик подключить еще к плате. У экрана порты GND VDD SCK SDA RES DS CS . К каким портам на плате чтоб соответствовало коду нужно будет подключить можешь подсказать? Я скинул новый код чуть выше
