DFRobot Heart Rate Sensor

Hey Ella,

Here’s another test you can perform, if you can upload and run this very simple script that I’ve written below so we can check to see whether there’s a proper output from the sensor that should assist in troubleshooting (Note: You can use CTRL+SHIFT+L to access the serial plotter to graph this output).

#define READ_PIN A1

void setup() {
  Serial.begin(9600);
  pinMode(READ_PIN, INPUT);
}

void loop() {
  Serial.println(analogRead(READ_PIN));
  delay(20);
}
