507_2_Smartsurface_Gradient

For the interface design, I use potentiometer (convenient to integrated with relay part) to control LEDs in order to show the gradient. Potentiometer converts voltage (0-5V) to a digital number between 0-1024. Therefor, if we want to control a serial of LEDs to turn on and remain turn on, we should assign each of them to specific number range.So if one condition (certain number range input from potentiometer) reached, the led will be turn on untill the condition disappear (poterntiometer move away from one range). 

Below is the code I wrote:

int sensorPin = 0;    

int ledPin1 = 1;     

int ledPin2 = 2;

int ledPin3 = 3;     

int ledPin4 = 4;

int ledPin5 = 5;     

int ledPin6 = 6;

int ledPin7 = 7;

int ledPin8 = 8;     

int ledPin9 = 9;     

int ledPin10 = 10;

int ledPin11 = 11;     

int ledPin12 = 12;

int sensorValue = 0;

void setup() {

   pinMode(ledPin1, OUTPUT);  

   pinMode(ledPin2, OUTPUT);  

   pinMode(ledPin3, OUTPUT); 

   pinMode(ledPin4, OUTPUT); 

   pinMode(ledPin5, OUTPUT);  

   pinMode(ledPin6, OUTPUT);  

   pinMode(ledPin7, OUTPUT); 

   pinMode(ledPin8, OUTPUT); 

   pinMode(ledPin9, OUTPUT);  

   pinMode(ledPin10, OUTPUT);  

   pinMode(ledPin11, OUTPUT); 

   pinMode(ledPin12, OUTPUT); 

}

void loop() {

   int threshold1 = 1020;

  if(analogRead(sensorPin) < threshold1){

    digitalWrite(ledPin1, HIGH);}

    else{ digitalWrite(ledPin1, LOW);}

    

    int threshold2 = 938;

  if(analogRead(sensorPin) < threshold2){

    digitalWrite(ledPin2, HIGH);}

    else{ digitalWrite(ledPin2, LOW);}

    

        int threshold3 = 853;

  if(analogRead(sensorPin) < threshold3){

    digitalWrite(ledPin3, HIGH);}

    else{ digitalWrite(ledPin3, LOW);}

    

            int threshold4 = 768;

  if(analogRead(sensorPin) < threshold4){

    digitalWrite(ledPin4, HIGH);}

    else{ digitalWrite(ledPin4, LOW);}

    

  int threshold5 = 683;

  if(analogRead(sensorPin) < threshold5){

    digitalWrite(ledPin5, HIGH);}

    else{ digitalWrite(ledPin5, LOW);}

    

    int threshold6 = 598;

  if(analogRead(sensorPin) < threshold6){

    digitalWrite(ledPin6, HIGH);}

    else{ digitalWrite(ledPin6, LOW);}

    

        int threshold7 = 512;

  if(analogRead(sensorPin) < threshold7){

    digitalWrite(ledPin7, HIGH);}

    else{ digitalWrite(ledPin7, LOW);}

    

         int threshold8 = 427;

  if(analogRead(sensorPin) < threshold8){

    digitalWrite(ledPin8, HIGH);}

    else{ digitalWrite(ledPin8, LOW);}

   

         int threshold9 = 342;

  if(analogRead(sensorPin) < threshold9){

    digitalWrite(ledPin9, HIGH);}

    else{ digitalWrite(ledPin9, LOW);}

    

    int threshold10 = 257;

  if(analogRead(sensorPin) < threshold10){

    digitalWrite(ledPin10, HIGH);}

    else{ digitalWrite(ledPin10, LOW);}

    

        int threshold11 = 172;

  if(analogRead(sensorPin) < threshold11){

    digitalWrite(ledPin11, HIGH);}

    else{ digitalWrite(ledPin11, LOW);}

    

            int threshold12 = 87;

  if(analogRead(sensorPin) < threshold12){

    digitalWrite(ledPin12, HIGH);}

    else{ digitalWrite(ledPin12, LOW);}

Put revised model in, just fit! (the support piece last week is smaller for LED to embedded in, I redo them~)

Light it up!!
