Introduction: Obstacle Preventing Car.

I modified a toy car into obstacle preventing car mean when some thing come in front of car it will turn. I keep it as simple as possible to be recreated. I use less expensive components.

All you need:

  • A simple toy car
  • Ultrasonic sound distance sensor
  • Arduino neon
  • A 9v battery
  • Some jumper wires
  • Two motor

I use two motor when need of turn arise one of that motor will be slow down causing the car to turn.

Step 1: Wiring.

Wiring is most simple part of this project just fallow the given systematic .

Step 2: Program the Arduino

The programing is simple it is given below.

Just fit all the component in the car and the ultrasonic sonic sensor must be out of the car in front.

const int trigPin = 12;
const int echoPin = 11;

long duration;
int distance;
void setup() {
pinMode(trigPin, OUTPUT); 
pinMode(echoPin, INPUT); 
pinMode(9, OUTPUT);
pinMode(10, OUTPUT);
pinMode(8, OUTPUT);
digitalWrite(10, HIGH);
digitalWrite(8,LOW);
digitalWrite(9, HIGH);
}
void loop() {
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance= duration*0.034/2;
delay(50);
if(distance<40 and distance>10);
{ digitalWrite(10, LOW);
delay(1000);
digitalWrite(10, HIGH);
}
 if (distance<10);
{ digitalWrite(10, LOW);
 digitalWrite(9,LOW);
 digitalWrite(8,HIGH);
 delay(1000);
 digitalWrite(10,HIGH);
 digitalWrite(8,LOW);
 digitalWrite(9, LOW);
delay(1000);
digitalWrite(9, HIGH);
}

Step 3: Finishing

Just put all of your component in the car and you are ready to go just power on and your ordinary car will prevent all obstacles and turn when wall or any thing come in front of car.

    Cool robot design. I like how the range sensor kind of makes it looks like Wall-E

    Only one minor critique, Noticed in the wiring diagram, Digital pin 8 is not connected to anything, so misc. code.. (a few bytes saved, but..) Nicely done though!!!

    sorry, actually common gnd of motors goes to pin 8.

    this will reverse the car if distance become less the 10.
