Description: Our project was to make a car that by using a sensor will drive itself and turn when presented with an object it could not drive through.
Description of Program: The program was set up so that the car would move indefinitely forwards until it reached an obstacle that triggered the push button mounted on the front by a whisker. Once triggered the program had the car reverse for one second and then turn for one second.
int motor1 = 12; //declares the first pin for the first motor
int motor2 = 7; //declares the second pin for the first motor
int motor3 = 8; // declares the first pin for the second motor
int motor4 = 13; // declares the second pin for the second motor
int motorpmw2 = 11; // this is the first pmw that will set how much battery power the motor is getting (speed)
int motorpmw = 6; // this is the second pmw that will set how much battery power the motor is getting (speed)
int button = 2; // declares the pin for the turn push button
int val = 0; // declares value for reading sensors
void setup()
{
pinMode(motor1, OUTPUT); //
pinMode(motor2, OUTPUT); // these simply are declaring them as outputs
pinMode(motorpmw, OUTPUT); //
pinMode(motor3, OUTPUT); //
pinMode(motor4, OUTPUT); //
pinMode(motorpmw2, OUTPUT); //
pinMode(button, INPUT); // declares button as an input
}
void loop()
{
analogWrite(motorpmw2, 255); // this is the analog speed value for the arduino (0-255)
analogWrite(motorpmw, 255); // this is the analog speed value for the arduino (0-255)
digitalWrite(motor1, LOW); //turns the motors on - forwards
digitalWrite(motor2, HIGH); //
digitalWrite(motor3, LOW); //
digitalWrite(motor4, HIGH); //
val=digitalRead(button); // sets value to be read from the button
if(val == HIGH) // this program only takes effect if the button is pushed
{ analogWrite(motorpmw2, 255); // this is the analog speed value for the arduino (0-255)
analogWrite(motorpmw, 255); // this is the analog speed value for the arduino (0-255)
digitalWrite(motor1, HIGH); //turns the motors on - backwards
digitalWrite(motor2, LOW); //
digitalWrite(motor3, HIGH); //
digitalWrite(motor4, LOW); //
delay(1000); // does previous direction for one second
analogWrite(motorpmw2, 255); // this is the analog speed value for the arduino (0-255)
analogWrite(motorpmw, 255); // this is the analog speed value for the arduino (0-255)
digitalWrite(motor1, HIGH); //turns the motors on - turns right
digitalWrite(motor2, LOW); //
digitalWrite(motor3, LOW); //
digitalWrite(motor4, HIGH); //
delay(1000); // does previous direction for one second
}
}
Various motor and battery problems were encountered and were fixed by tampering with the circuitry and creating new pieces
Things we would like to add would be a way to control the car without a whisker(such as infrared sensors) and getting a new car base
