How to hook up Blender Python script with Arduino? I am trying to make a hologram were a series of propellers spin and emit lights to give off the hologram. I was planning on making the lights come on when they are touching an object inside Blender. What I mean by this is on each "propeller" a strip of lights are on each blade and it simulates this in Blender with accelerometers in 3D space. I want to know how to hook Blender up with the Arduino online editor and be able for them to correspond and transmit messages and signals.
You cannot 'hook Blender up with the Arduino online editor', however you can have a program running on the Arduino that would communicate with a Python script running in Blender over serial connection(USB). Have a look at pyserial. You might probably be interested in application handlers in Blender as well.
