Self-Driving Car

Made by Steve DePaulis, Paul Kinder, and Kam Kosowski

Description: Our project was to try to make a car drive by itself and, when presented with an obstacle, will reverse and turn to face a new direction.

Description of program: The program was set up to keep moving forward while the wheels move back and forth and maintain a steady path. When the car runs into an obstacle, it will reverse and turn to face a new direction and proceed to move forward.

int motor1 = 7; // declares the first pin for the first motor

int motor2 = 8; // declares the second pin for the first motor

int motor3 = 12; // declares the first pin for the second motor

int motor4 = 13; // declares the second pin for the second motor

int motorpmw = 10; // declares the pmw pin the will control the power to the motor

int motorpmw2 = 9; // declares the second pmw pin that will control the power to the motor

int button = 2; // declares the pin for the push button

int val = 0; // declares value for reading sensors

void setup()

{

pinMode(motor1, OUTPUT); // declares them as outputs

pinMode(motor2, OUTPUT); //

pinMode(motorpmw, OUTPUT); //

pinMode(motor3, OUTPUT); //

pinMode(motor4, OUTPUT); //

pinMode(motorpmw2, OUTPUT); //

pinMode(button, INPUT); // declares button as an input

}

void loop()

{

analogWrite(motorpmw, 255); // analog speed for arduino (0-255)

analogWrite(motorpmw2, 255); // analog speed for arduino (0-255)

digitalWrite(motor1, HIGH); // turns the back motors on and makes the car go forward

digitalWrite(motor2, LOW); //

digitalWrite(motor3, HIGH); // turns the front motors on and turns right

digitalWrite(motor4, LOW); //

delay(500); // delays how long its turned

digitalWrite(motor3, LOW); // turns the front motors on and turns left

digitalWrite(motor4, HIGH); //

delay(500); // delays how long its turned

val=digitalRead(button); //sets the value that is read by the button

if(val == HIGH) // this only happens if the button is pushed

{

analogWrite(motorpmw, 255); // analog speed for arduino (0-255)

analogWrite(motorpmw2, 255); // analog speed for arduino (0-255)

digitalWrite(motor1, LOW); // turns the back motors on and makes the car go backward

digitalWrite(motor2, HIGH); //

digitalWrite(motor3, HIGH); // turns the front motors on and turns right

digitalWrite(motor4, LOW); //

delay(2000); // delays how long it reverses and turns backward

}

}

Some of the problems that we ran into were that some of the wiring was touching without any insulation which caused the board to malfunction. We had a few troubles with writing the program.

If we had more money, we would make a better push button system that was more effective. I think we would make the board more clean and not have wire everywhere.
