💻 Sample Arduino Code:

char data = 0;
void setup()
{
Serial.begin(9600);
pinMode(8, OUTPUT);
pinMode(9, OUTPUT);
pinMode(10, OUTPUT);
pinMode(11, OUTPUT);
}
void loop()
{
if(Serial.available() > 0)
{
data = Serial.read();
Serial.print(data);
Serial.print(“\n”);
if(data == ‘a’)
digitalWrite(8, HIGH);
else if(data == ‘b’)
digitalWrite(8, LOW);

if(data == ‘c’)
digitalWrite(9, HIGH);
else if(data == ‘d’)
digitalWrite(9, LOW);

if(data == ‘e’)
digitalWrite(10, HIGH);
else if(data == ‘f’)
digitalWrite(10, LOW);

if(data == ‘g’)
digitalWrite(11, HIGH);
else if(data == ‘h’)
digitalWrite(11, LOW);
}
}

This kit is a fun and practical introduction to Arduino robotics. Assemble your car, upload the code, and watch it navigate smartly around obstacles on its own.
