Arduino Analog Inputs

Now we modify the constants const section at the start of the sketch to increase the number of analog inputs to 6. Note that the first analog input is a0 and the sixth analog input is A5.
I copied the first line, pasted it 5 times and then changed the analog input number A1 – A5 and description note to // pin that LDR is attached to. You can just copy and paste this code if you want to:
const int analogPinA0 = A0; // pin that LDR1 is attached to
const int analogPinA1 = A1; // pin that LDR2 is attached to
const int analogPinA2 = A2; // pin that LDR3 is attached to
const int analogPinA3 = A3; // pin that LDR4 is attached to
const int analogPinA4 = A4; // pin that LDR5 is attached to
const int analogPinA5 = A5; // pin that LDR6 is attached to

Next I added 5 more LED’s by adding the code 
const int ledPin13 = 13; // pin that the LED is attached to for A0 LDR1
const int ledPin12 = 12; // pin that the LED is attached to for A1 LDR2
const int ledPin11 = 11; // pin that the LED is attached to for A2 LDR3
const int ledPin10 = 10; // pin that the LED is attached to for A3 LDR4
const int ledPin9 = 9; // pin that the LED is attached to for A4 LDR5
const int ledPin8 = 8; // pin that the LED is attached to for A5 LDR6
I expanded the comment to add the number of the LED that was for the analoge input. When adding your 6 LED’s to the digital outputs remember to add a 220 ohm resistor in series with each LED as a current limiter.

Then we need to set up six digital output pins for the LED’s
pinMode(ledPin13, OUTPUT);
pinMode(ledPin12, OUTPUT);
pinMode(ledPin11, OUTPUT);
pinMode(ledPin10, OUTPUT);
pinMode(ledPin9, OUTPUT);
pinMode(ledPin8, OUTPUT);

  // read the value of the LDR:
int analogValueA0 = analogRead(analogPinA0);
delay(5); // delay in between reads for stability was 1
int analogValueA1 = analogRead(analogPinA1);
delay(5); // delay in between reads for stability was 1
int analogValueA2 = analogRead(analogPinA2);
delay(5); // delay in between reads for stability was 1
int analogValueA3 = analogRead(analogPinA3);
delay(5); // delay in between reads for stability was 1
int analogValueA4 = analogRead(analogPinA4);
delay(5); // delay in between reads for stability was 1
int analogValueA5 = analogRead(analogPinA5);
delay(5); // delay in between reads for stability was 1

The next section of code turns the LED on if the LDR is covered.
// if the analog value is high enough, turn on the LED:
if (analogValueA0 > threshold) {
digitalWrite(ledPin13, HIGH);
} else {
digitalWrite(ledPin13, LOW); // LED 13 works
}
if (analogValueA1 > threshold) {
digitalWrite(ledPin12, HIGH);
} else {
digitalWrite(ledPin12, LOW); // This flashes LED’s 2-6
}
if (analogValueA1 > threshold) {
digitalWrite(ledPin11, HIGH);
} else {
digitalWrite(ledPin11, LOW);
}
if (analogValueA1 > threshold) {
digitalWrite(ledPin10, HIGH);
} else {
digitalWrite(ledPin10, LOW);
}
if (analogValueA1 > threshold) {
digitalWrite(ledPin9, HIGH);
} else {
digitalWrite(ledPin9, LOW);
}
if (analogValueA1 > threshold) {
digitalWrite(ledPin8, HIGH);
} else {
digitalWrite(ledPin8, LOW);
