Hi,

Has anyone tried recording RPM measurements using an Eagle Tree Optical RPM Sensor ? For a project i need to mesure the RPM of my brushless motor.

My code :

 // FREQUENCE INPUT PIN => pin 5 pr aduino uno
#include <FreqCount.h>
int RPM;
int count;
int nb_pole=14;

void setup() {


  Serial.begin(9600);

  FreqCount.begin(1000); //intervale de mesure en millisec
  
}

void loop() {
  if (FreqCount.available()) {
    unsigned long count = FreqCount.read();

//RPM=(count*60)/nb_pole;

    Serial.println(RPM);
    
    

  }
}
 

Actually i have only bad values.. When the motor is stopped i have "50". 

Thanks
