AD8232 ECG sensor

Other Hardware Sensors

Good morning everyone,

Last week i bought AD8232 sensor from AliExpress. When i unpacked it, pluged in to my Arduino Leonardo and make some coding i hoped that this will work. Unfortynately i was wrong. My serial everytime looks like this:

If we talk about leads it's okey connected, but this signal only oscilate between zero and some maximul value. Can you help me with this problem?

There are many ways to configure and use a AD8232. Why not make a drawing of how you are using it and add a description, as well.

Okey, so i think that i am using it in the simplest way that i can. The shema of connections is like this:

If we talk about leads, i used a connection to arms and leg. Last thing i find in the internet guides is the code:

void setup() {
  Serial.begin(9600);
  pinMode(10, INPUT); // Setup for leads off detection LO +
  pinMode(11, INPUT); // Setup for leads off detection LO -

}

void loop() {
  if((digitalRead(10) == 1)||(digitalRead(11) == 1)){
    Serial.println('!');
  }
  else{
      Serial.println(analogRead(A0));
  }
  delay(1);
}

It is very funny, that i search a lot in the internet, and a lot of people with the same connections and code is happy with their result. Unfortynately not in my case :confused:
