Hi,

Im not looking to display anything I just want to give a false VSS above 40 mph, Ive done a bit of research and come up with this. would this work?

void setup() {
  // put your setup code here, to run once:
  const int hardwareCounterPin = 5;
  const int samplePeriod = 1000; 
  unsigned int count;
  unsigned int vssout;
}

void loop() {
  
  bitSet(TCCR1B, CS12); 
  bitSet(TCCR1B, CS11); 
  delay(samplePeriod); 
  TCCR1B = 0; 
  count = TCNT1; 
  TCNT1 = 0;     
  if (count > 88) int vssout = 222;
  if (count  <11) int vssout = 0;
  analogWrite(pin, vssout);


}
