Hi, I am trying to measure the time between the rising and falling edge on the pin D2. I have attached a Sharp GP2Y0D815Z0F and it works quite good despite the bouncing. Now i would like to know how long I hold my hand in front of the sensor. So i tried to use the interrupt function. My current c…

Take a look at this topic [image] Subtitute for function pulseIn Firmware I i have a problem the sketch that i have for my arduino have one function called pulseIn and the Bluid from spark doesn’t recognize, anyone know how to…

thank you very much for your pointer! However it does not seem to work properly. My code: void setup() { Serial.begin(9600); Serial.println("Setup"); pinMode(D2, INPUT); } void loop() { long duration; duration = pulseIn(D2, HIGH); Serial.print(duration); …

The code seems to output random numbers when I put my hand in front of the sensor. I am also not exactly sure what the pulseIn code does. So any help would be greatly appreciated :smile: Output: 0 ms 0 ms 0 ms 0 ms 0 ms 0 ms 1085424 ms 1087 ms 1701 ms 1700 ms 1702 ms 10203 ms 431 ms 1701 ms 552 ms…
