Light Sensitive Worm Using Arduino Uno

Hey guys, after a long time I am writing. I hope you guys are all good. Today I am writing an easy instructable but you will get fun from it, confirmed!

1.Arduino Uno

2.LDR(light dependent resistor)

3.LED (10 pieces)

4.Resistor(100 ohm and 100K)

5.Male to Male jumpers

6.Bread board

int LDRvalue=0;

int LDRsensitivity=400;

void setup()

{ pinMode(13,OUTPUT);

pinMode(12,OUTPUT);

pinMode(11,OUTPUT);

pinMode(10,OUTPUT);

pinMode(9,OUTPUT);

pinMode(8,OUTPUT);

pinMode(7,OUTPUT);

pinMode(6,OUTPUT);

pinMode(5,OUTPUT);

pinMode(4,OUTPUT);

Serial.begin(9600); }

void loop() {

int i=13;

int j=12;

for(int k=0;i<=13&&i>=4&&j<=12&&i>=4;k=k+1){

LDRvalue=analogRead(A0);

Serial.println(LDRvalue);

if(LDRvalue>LDRsensitivity){

Serial.println(i);

Serial.println(j);

digitalWrite(i,HIGH);

digitalWrite(j,HIGH);

delay(100);

digitalWrite(i,LOW);

digitalWrite(j,LOW);

i=i-1;

j=j-1;

delay(100);

}

else{

Serial.println(i);

Serial.println(j);

digitalWrite(i,HIGH);

digitalWrite(j,HIGH);

delay(100);

digitalWrite(i,LOW);

digitalWrite(j,LOW);

i=i+1;

j=j+1;

delay(100);

}

}

}

Thank You.
