Easy Line Following Robot with Arduino! 

Heres' the code guys: #include AF_DCMotor motorA(4); //this is the left motor AF_DCMotor motorB(2); //this is the right motor void setup() { Serial.begin(9600); // set up Serial library at 9600 bps Serial.println("Line Follower Rover"); delay(500); pinMode(A0, INPUT); // declare A0 as input pin for left sensor pinMode(A1, INPUT); // declare A1 as input pin for right sensor motorA.setSpeed(180); // turn on motor1 motorA.run(RELEASE); motorB.setSpeed(180); // turn on motor2 motorB.run(RELEASE); } void loop() { int sensor1 = digitalRead(A1); int sensor2 = digitalRead(A0); //Reading the values of the sensors on the serial monitor Serial.print(sensor1); Serial.print(" "); Serial.println(sensor2); delay(50); //value of 0 means no black line, value of 1 means black line detected. //Move forward if both sensors zero (no black line). if ((sensor1 == 1) && (sensor2 == 1)) { motorA.setSpeed(200); // turn on motor1 motorB.setSpeed(200); motorA.run(FORWARD); motorB.run(FORWARD); } //Turn left if left sensor (sensor 1) detects black line else if ((sensor1 == 0) && (sensor2 == 1)) //motor1 is left motor, motor 2 is right motor { motorA.setSpeed(200); // turn on motor1 motorA.run(FORWARD); motorB.setSpeed(50); motorB.run(FORWARD); } //Turn right if right sensor detects black line else if ((sensor2 == 0) && (sensor1 == 1)) //motor1 is left motor, motor 2 is right motor { motorA.setSpeed(50); // turn on motor1 motorA.run(FORWARD); motorB.setSpeed(200); motorB.run(FORWARD); } }

uhm, where are the double A batteries connected??? the 5v was the only one explained where to connect in the motor driver

Can u plz make videos on how to control a robot car by MEMS sensor??

How can i build a line following robot for multiple paths detection

shows stray error

Can you make this project for 4 motors instead of 2? please

Hey! Im a beginner. I bought chasis the man there handed me chasis connected with 4 wheels and 4 DC motos now I don't understand the connection for 4 motors and code too. I m thinking to just get some wholes on any tough plastic at home and make my own? plz let me know about the connection else I can make a new chasis. Im confused.

how did you use two power supplies

How do you make a robot turn on a straight line ??

Perfect

How volt does it need

Good job

Hi teacher i have a problem in my project please make a vedio about using l293d motor driver with fire sensor and servo.

cn i use hiwat 9v battery of 20 rs

sir may you send me the link of the program

Is it just me or does the "//" explanation not quite add up, because if your car steers to the right and you increase the speed of the left wheel and decrease the speed of the right wheel, won't the car keep steering to the right?

Your path is too wide bro

I have a IR sensor array which has ports like, "VCC,GND,S1,S2,S3,S4,S5,CLP,Near". How can I connect it? I am facing problem in connection. Can you please help me out? Can I have your facebook ID or anything so that I can directly contact with you?

can

Sir.. thanks for your videos. I got 1 questions if you can answer. 1) can we used different motor driver such as l29d instead of this?
