Simplified lamp software algorithm

Define constants for pins e.g. #define LED_RED 9
Instantiate hueRotart, saturationRotary and bluetooth software serial
Run void setup() { ... }
1. Run startup sequence R => G => B => GB => RB => RG => RGB (helps with checking if colors are hooked up correctly
2. Begin listening for bluetooth serial on 9600 rate
3. Begin listening for hueRotatary and saturationRotary
4. Setup brightness controls pins VALUE_INCREASE and VALUE_DECREASE to INPUT_PULLUP to avoid faulty readings
Run void loop() { ... } in loop

Concrete	25 PLN (~7$)	5 kilograms of fast-dry (1h) concrete. We used about one-third of it.
Wood	40 PLN (~10$)	I bought some low-quality pine planks, which we later painted. I recommend investing a bit more in a better type of wood if you can.
