CODE 4/6 - Lighting LEDs using Array

int ledPin = 3;//declare led pin

int photoPin = 0;//declare the analog reading pin

int photoValue = 0;//declare value to store the analog value

int brightness = 0;//declare variable to store and pass the analog value to the led

void setup() { pinMode(ledPin, OUTPUT);//declare output pin

pinMode(photoPin, INPUT);//declare input pin

Serial.begin(9600); }

void loop() {

photoValue = analogRead(photoPin);//read the analog values from the photocell/flexing sensor

brightness = photoValue;//pass analog value from the analog read varibale to the led brightness variable

Serial.println(brightness);//print value received from the photocell/flexing sensor

analogWrite(ledPin, brightness);//pass the analog value to adjust brightness

delay(200);//remove noise

CODE 5/6 - Lighting LEDs using Array

The goal here was to have 3 LEDs in one array and 3 led in a different so I can light them up fast from the center of the row to the ends and when pot turned all the way to the other side then it changes the direction and speed.

The issue was that I could not figure out how to make the two different arrays to be doing the same thing at the same time. That is why I took the i that i used as a delay timer and put actual numbers

int pinArray[] = { 2, 3, 4 }; //declare first array that includes pins 2 through 4

int pinArray2[] = { 5, 6, 7}; //declare a second array that includes pins 5 through 7

int arrayVal = 2; //declare a variable to hold the array values;

int arrayVal2 = 0;

int switchPin = 10;

int switchPin2 = 9;

int switchstate = HIGH;

void setup() {

pinMode(switchPin, INPUT);

pinMode(switchPin2, INPUT);

for ( arrayVal = 2; arrayVal >= 0; arrayVal-- ){ //use the for statement to go through all numbers from the array - from 4 to 2

pinMode(pinArray[arrayVal], OUTPUT); //set all pins from that array to be output

}

for ( arrayVal2 = 0; arrayVal2 <=2 ; arrayVal2++ ){ //use the for statement to go through all numbers from the array - from 5 to 7

pinMode(pinArray2[arrayVal2], OUTPUT); //set all pins from that array to be output

}

}

void loop() {

int state = digitalRead(switchPin);

int state2 = digitalRead(switchPin2);

if ( state != switchstate){

for (arrayVal = 2; arrayVal>=0; arrayVal--){ //test pins in backwards order (from higher number to lower)

//for ( i = 0; i<2000;>

digitalWrite(pinArray[arrayVal], HIGH);

delay(100);

digitalWrite(pinArray[arrayVal-1], HIGH);

delay(100);

digitalWrite(pinArray[arrayVal], LOW);

delay(100);

}

for (arrayVal2 = 0; arrayVal2 <= 2 ; arrayVal2++){ //test pins going from lower number to higher

digitalWrite(pinArray2[arrayVal2], HIGH); //light up led in a fluid manner

delay(100);

digitalWrite(pinArray2[arrayVal2+1], HIGH);

delay(100);

digitalWrite(pinArray2[arrayVal2], LOW);

delay(100);}

}

else{

for(arrayVal=0; arrayVal<=2; arrayVal++){ //test pins going from lower number to higher

digitalWrite(pinArray[arrayVal], HIGH); //light up led in a fluid manner

delay(40);

digitalWrite(pinArray[arrayVal+1], HIGH);

delay(40);

digitalWrite(pinArray[arrayVal], LOW);

delay(40);

}

for (arrayVal2 = 2; arrayVal2 >= 0; arrayVal2--){ //test pins going from higher number to lower number

digitalWrite(pinArray2[arrayVal2], HIGH);

delay(40);

digitalWrite(pinArray2[arrayVal2-1], HIGH);

delay(40);

digitalWrite(pinArray2[arrayVal2], LOW);

delay(40);

}

}
