Using 7 dual #opamps (LM358) to generate PWM signals for driving a non-addressable RGB LED strip so that only one linear potentiometer is needed to sweep through the colours of the #rainbowFlag

Project inspired by

in which @blitzcitydiy used a microcontroller to map a potentiometer to the range of hues

Welp. I’ve only coded the UI so far, and even then I’m unsure why the top two rows of pixels are glitchy. But the new Feather works, so I guess I’d better start writing the @hackaday project page! #opampchallenge
