Control Box

To test different background patterns for the wall, I wanted to build a sort of control box. I bought a variety of potentiometers- slides and knobs a while back and I can put them to use. so I designed a box and got it laser cut.

Amazingly everything fit the first time.

Inside there is breadboard to hold all of the fixed items as well as arduino.
I wrote a test program for each of the different elements-lcd, knobs, slides and buttons.

Slider Test

Here is the code to test the sliders

#include <LiquidCrystal.h>



const byte redSliderPin   = 0;

const byte greenSliderPin = 1;

const byte blueSliderPin  = 2;

const byte whiteSliderPin = 3;



// Init our Input Vars

byte redSlider;

byte greenSlider;

byte blueSlider;

byte whiteSlider;



// initialize the library with the numbers of the interface pins]

LiquidCrystal lcd(2, 3, 4, 5, 6, 7);



void setup() {

// set up the LCD's number of rows and columns: 

lcd.begin(16, 2);

}



void loop() {



redSlider   = analogRead(redSliderPin)/4;

greenSlider = analogRead(greenSliderPin)/4;

blueSlider  = analogRead(blueSliderPin)/4;

whiteSlider = analogRead(whiteSliderPin)/4;



// set the cursor to column 0, line 1

// (note: line 1 is the second row, since counting begins with 0):

lcd.setCursor(0, 0);

lcd.print("R: ");

lcd.print(redSlider,DEC);

lcd.print('  ',BYTE);



lcd.setCursor(8, 0);

lcd.print("G: ");

lcd.print(greenSlider,DEC);

lcd.print('  ',BYTE);



lcd.setCursor(0, 1);

lcd.print("B: ");

lcd.print(blueSlider,DEC);

lcd.print('  ',BYTE);



lcd.setCursor(8, 1);

lcd.print("W: ");

lcd.print(whiteSlider,DEC);

lcd.print('  ',BYTE);

}
