Remote Control Car by Ian, Wani and Barrett

For this project we built a remote control car with a sensor so it doesn't hit anything. The car will move forward when we press up on the remote and move backwards when press down on the remote.

• Vex Dc kit
• Arduino
• 14 Wires
• Bolts

To build the body of the car we used vex dc kit. First we connected four wheels to the vex plate using nuts and bolts. We placed the bigger wheel in the back and the smaller wheels in the front.

Then we connected the motors to the two back wheels with the wires being connected to the breadboard. After doing this we made a little spot for the battery towards the front of the car.

This is the circuit that we made to control the car. Use this wiring diagram to replicate it.

This is the code we made to make the car go forward and backwards using an IR remote.

#include

int IRPin = 6; //the pin the IR receiver is connected to

int enablePin = 11; // the pin to turn on the car

int in1Pin = 10; //the pin to make the car go forward

int in2Pin = 9; //the pin to make the car go backwards

void setup()

{

Serial.begin(9600);

IrReceiver.begin(IRPin);

pinMode(6,OUTPUT);

pinMode(11,OUTPUT);

pinMode(10,OUTPUT);

pinMode(9,OUTPUT);

}

void loop()

{

if (IrReceiver.decode())

{

int IRcode = IrReceiver.decodedIRData.command;

if (IRcode == 67)

{

Serial.println(IRcode);

}

IrReceiver.resume();

}

int IRcode = IrReceiver.decodedIRData.command;

if (IRcode == 67)

{

digitalWrite(enablePin,HIGH);

digitalWrite(in1Pin,HIGH);

digitalWrite(in2Pin, LOW);

}

else if (IRcode == 68)

{

digitalWrite(enablePin,HIGH);

digitalWrite(in1Pin,LOW);

digitalWrite(in2Pin, HIGH);

}

else

{

digitalWrite(enablePin,HIGH);

digitalWrite(in1Pin,LOW);

digitalWrite(in2Pin, LOW);

}

}
