Hello, I am trying to write a script that would run on startup to check if openvpn server is running and if so light up a pixel on a blinkt. I am okay with the programming of a loop to check every 5 minutes if a variable is 1 and how to light the pixel but i need help checking the status of the open...

accurate rotation of a motor

Good evening, I am working on an idea to projection map a rotating object turned by a motor mounted above it. The total piece of work will be 40 seconds long and loop continuously, I am going to (hopefully) use openFrameworks to map the content to the object but need your advice regarding rotating t...
