Ардуино-спидометр.

[metaforos]

А я вот так меряю скорость и расстояние :

const int  DsaPin = 8;    
int DsaPulseCounter = 0;  
int DsaState = 0;         
int LastDsaState = 0; 
int meters;
unsigned long  pulseTime = 0; 
unsigned long  thisTime = 0;
unsigned long  lastTime = 0;
unsigned long  mySpeed = 0;

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

void loop() 
{
odometer();
}

void odometer()
{
  DsaState = digitalRead(DsaPin);
  if (DsaState != LastDsaState) 
  {
    if (DsaState == HIGH) 
    {
        lastTime = thisTime;
        thisTime = micros();
        pulseTime = thisTime - lastTime;
        int mySpeed = (3600000000/pulseTime*15)/100000;
        
     DsaPulseCounter++;
     meters = DsaPulseCounter/6.66;
     Serial.println(meters, DEC);
     Serial.println(mySpeed);
    } 
  }
  LastDsaState = DsaState;
}
