Yolo in conjonction with Ultrasonic sensor

So, I was working on a script to get Yolo starting only if an object is presented at the correct distance (1.0meter) using a Ultrasonic sensor.

This works nice.

@moz4r, I solved the neopixel issue by adding an extra sleep(4) at the beginning of my script.

I adjusted the initial rotation of the virtual inmoov jaw so that its no longer screaming, but in the same pull request I fixed the unbridled update.   What's this about ?

Hi, this is not directly about MyRobotlab but the goal of the project is the creation of new Material for our beloved Robots, so I hope to get some help here. And my last attempt ended with a big bunch of blue expensive smoke.

Hi MaVo, this was an Arduino Uno - I had some problems with subscribing to publishPin, but this worked for my setup.  I just enabled pin 14 which is an analog pin and a stream of values became accessable.

 

You should be able to add or remove from streaming array of PinData with more enables or disables
