DIY 2WD Robot Car: Building, Coding, and Transforming! Step-by-Step Guide with Arduino

Code:

 // the setup function runs once when you press reset or power the board

int leftf1=7;

int leftf2=6;

int rightf1=5;

int rightf2=4;

void setup()

{

  // initialize digital pin LED_BUILTIN as an output.

 

    pinMode(leftf1, OUTPUT);

    pinMode(leftf2, OUTPUT);

    pinMode(rightf1, OUTPUT);

    pinMode(rightf2, OUTPUT);

 

}

// the loop function runs over and over again forever

void loop()

  {

 forward();

 delay(1000);

 reverse();

 delay(1000);  

   }

void forward()

{

   

  digitalWrite(leftf1,LOW);   // turn the LED on (HIGH is the voltage level)

  digitalWrite(leftf2, HIGH);   // turn the LED on (HIGH is the voltage level)

  digitalWrite(rightf1, HIGH);   // turn the LED on (HIGH is the voltage level)

  digitalWrite(rightf2, LOW);   // turn the LED on (HIGH is the voltage level)    // wait for a second

     

  }

  void reverse()

  {

   

  digitalWrite(leftf1, HIGH);   // turn the LED on (HIGH is the voltage level)

  digitalWrite(leftf2, LOW);   // turn the LED on (HIGH is the voltage level)

  digitalWrite(rightf1, LOW);   // turn the LED on (HIGH is the voltage level)

  digitalWrite(rightf2, HIGH);   // turn the LED on (HIGH is the voltage level)
