Simple NeoPixel Driver
As part of set design we needed to create a simple NeoPixel driver. NeoPixels are strips of LEDs where each of the LEDs can be set to a particular RGB value.
However we wanted to go further and create some dynamic patterns with effects and transitions to go between each LED scene.
We coded the maths and driver on a Pi Zero and then used Flask to create a responsive web site that coould be driven by either automation or a production assistant.
