I am trying to analyze ECG signals with AD8232 heart rate sensor and Arduino uno. I've looked up nearly every website and I am exactly using the same code and same sensor. But my output is nothing like the pictures. In examples you can clearly see the QRS Waves but in my output I cannot. I am thinking that maybe my sensor is oversampling but I also couldn't find what is the sample rate of it and how to change it. If you know how to solve this problem please let me know. You can see the code I use and the output. void setup() { // put your setup code here, to run once: Serial.begin(9600); pinMode(10,INPUT); pinMode(11,INPUT);

} void loop() { // put your main code here, to run repeatedly: if((digitalRead(10)==1) || (digitalRead(11)==1)){ Serial.println("!"); }else{

Serial.println(analogRead(A0)); } delay(1); }
