Analog input

[perigalacticon]

I thought of idea to have an analog input or adc to allow users to interact with the lights such as a knob or slider or encoder.  Is there a way to have fpp read numerical values from some source such as serial, I2C, or SPI and then use them to affect properties of the display such as colors or speed or other aspects of effects or sequences?  Sort of a real-time xLights effectsvuser control.

That's a cool idea. I don't think FPP itself will help with either part. 

On the first part, you could GPIO it within FPP and make it do stuff on command. But not quite the same as having full control like with a knob or slider or encoder.

The second part is much harder to do adhoc. I don't think FPP can play a sequence at a faster or slower rate. FSEQ and FPP work in sync to keep things in sync. Something you might do is if there are limited selections, you could trigger different sequences to play on different inputs. But not really the full range of control you envision.
