Remote Color Picker for House LEDs

I wanted to get just the right color on my house LEDs to emulate the warm color of patio lights. So, I built a remote control that has knobs for the red, green, and blue colors and an OLED display to show the RGB values. It connects via WiFi (mesh) to the house LEDs, so I can see them live while standing in the yard.
The ESP8266 modules allow the WiFi connection, and I was using them already for the house LEDs since they need more RAM than an Arduino offers. I have a web site controlling the house LEDs for some holidays, and I have used app based control setups like Blynk, but the visceral feel of turning a knob while watching the colors change is really nice. I made a push button color picker before, and the potentiometers are easier to use.
The color picker can also be used stand-alone to get the right colors for various holidays (like the perfect orange for Halloween) and events.”
