Displaying of different color coding formats using analog led.

school arduino project which actually taught me arduino. i had limited supplies so i made it using little amount of things so basically theres a potentiometer which you can adjust value for the selected letter of RGB, HSV, HSL CMYK. left button for selecting element (r|gb,rg|b,rgb|,r|gb) right button for selecting color modes: (RGB, HSV, HSL CMYK)

ingredients:

arduino uno a pinchful of male-male jumper cables breadboard 10k potentiometer (values between 0, 1023. look i didn't have specifications for the component, components were gifted to me in a box that didn't provide any info of material) two buttons 3x 330 Ohm resistor 4x 460 Ohm resistor (button tutorial told me i need a 10k Ohm resistor for each button but i didn't have any. if you build like i did, electronics too close to your breadboard will interfere with your input. it does on mine. anyways, buttons get 920 Ohms each.) 1x RGB LED (anode led, runs in 5v)
