How to convert (almost) any 27 or 49 MHz RC Car into a Robotic car

Step 9 Arduino code example

#define FWR 3
#define BACK 5
#define RIT 7
#define LEFT 9

void setup() {
  // put your setup code here, to run once:
   pinMode(FWR,OUTPUT);
   pinMode(BACK,OUTPUT);
   pinMode(RIT,OUTPUT);
   pinMode(LEFT,OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
   analogWrite(FWR,100);
   digitalWrite(RIT,HIGH);
   delay(1000);
  
   analogWrite(FWR,0);
   digitalWrite(RIT,LOW);
   delay(1000);
  
   analogWrite(BACK,100);
   digitalWrite(LEFT,HIGH);
   delay(10000);
  
   analogWrite(BACK,0);
   digitalWrite(LEFT,LOW);
   delay(1000);
}
