Ultrasound sensor, Arduino, playing movie, using build-in Camera

Anita

Hello everyone,

I am trying to get an ultrasound sensor to read the distance of a person. —When the person is far it should trigger a movie to play. —When the person is at mid distance camera should activate and should film him. When the person is near to the sensor, there should be again a movie being played. At the point the code was reading the distances properly but when the camera was added the distance sensor didn't work anymore or it didn't give me the values anymore, only the camera appears to be activated, but it doesn't show any picture. At use there are a MacBookPro, Build-in Camera, Arduino Uno, Ultrasound sensor and Processing... I am including the code maybe a soul can shed a light!

Thanks so much in advance, Ana

void serialEvent(Serial cPort) { comPortString = cPort.readStringUntil('\n'); if(comPortString != null) { comPortString=trim(comPortString);

// Use the distance received by the Arduino to modify the lines distance = int(map(Integer.parseInt(comPortString),1,200,1,height)); println(distance);

// Values from 100 to 5000 if (distance < 1000) { // Play video 2 (dancing) output = 2; } else if (distance < 2500) { // Play video feed from camera (person) output = 1; } else { // Play video 1 (dancer sitting) output = 0; } }

Thanks for the tip! I just included the formated code. )
