Light sensitive robot

LIGHT SENSITIVE ROBOT

In this tutorial you will learn how to create a robot thats sensitive to light 

MATERIALS REQUIRED

1.Arduino uno

2.Tank chasis 

3.Adafruit motor shield

4.screws and spacer stud

5.Male to Female jumper wire x 3

6.Light dependent resister module(LDR)

CIRCUIT

1.LDR analog pin-A0

2.LDR Digital pin-Not connected

3.LDR GND -Arduino GND

4.LDR VCC - Arduino 5v

5.Motor terminals -M1,M2 of Motor sheild

CODE

#include <AFMotor.h>

const int LDR =A0;

AF_DCMotor motor1(1);

AF_DCMotor motor2(2);

void setup() {

  Serial.begin(9600);  

  pinMode(LDR,INPUT);

    motor1.setSpeed(200);

  motor1.run(RELEASE);

    motor2.setSpeed(200);

  motor2.run(RELEASE);

}

void loop() {

  int LDRstate= analogRead(A0);

  Serial.println(LDRstate),  delay(200);

  if(LDRstate>350){

    motor1.run(FORWARD);

    motor2.run(BACKWARD);

    }

    else{

      motor1.run(FORWARD);

      motor2.run(FORWARD);

      }
