wvmarle:
Then measure for 10 seconds and stop:bool measuring = false;
unsigned long startMeasuring;
void loop() {
if (measuring == false) {
// Start measuring.
measuring = true;
startMeasuring = millis();
}
if (millis() - startMeasuring < 10000) {
measureBPM();
}
else {
processBPM();
// To do another measurement, trigger the first if block again:
measuring = false;
}
}
I'll try it and tell you soon
