We are about to switch to a new forum software. Until then we have removed the registration on this forum.
Hello, my project intention is to track a face with OpenCV/Processing and try and center your face with two servos controlles by an arduino. I can confirm that communication between Processing and Arduino does work, my problem is that, suddenly when i run the processing sketch, there is no incoming video although a couple of hours ago it was working. I am using Processing 3.3.5 and Arduino 1.8.2. Also, i'd like to use Firmata as serial does not appear to work for me. I'd also like to add i am not too experienced with Processing nor Arduino.
Thank you in advance.
