IR vehicle with Arduino

The IR vehicle is a simple project, a car with Arduino, that receives an infrared signal from a remote control to control 2 servomotors.

IR vehicle material list

  • Arduino Uno.
  • IR receiver module KY-022.
  • IR remote control.
  • 2 Li-Ion 3.7V/2600mAh rechargeble batteries.
  • A switch with 3 terminals and 1 pole.
  • Wires for connection between components.
  • 2 SM-S4303R Springrc servomotors, which can turn 360º, like a common motor. Only servos with this feature can be used in this project.
The electronic part schematics.

Wheels that fit on servos were 3D printed.

 

 

 

 

An ex-printed circuit board serves as chassis.
The complete vehicle.

Algorithm

This code uses commands seen in 3 and 8 parts of Arduino tutorial.

#include <IRremote.h>
#include <Servo.h>

#define IR_RECEIVE_PIN 8

Servo servo1,servo2;
int posservo1,posservo2;

void setup(){
  Serial.begin(9600);
  IrReceiver.begin(IR_RECEIVE_PIN);
  servo1.attach(5);
  servo2.attach(6);
  servo1.write(90);
  servo2.write(90);
}

void loop(){
  if (IrReceiver.decode()) {
    IrReceiver.resume();
    Serial.println(IrReceiver.decodedIRData.command);
  }
  if(IrReceiver.decodedIRData.command==22){
    servo1.write(60);
  }
  else if(IrReceiver.decodedIRData.command==12){
    servo1.write(90);
  }
  else if(IrReceiver.decodedIRData.command==8){
    servo1.write(140);
  }
  else if(IrReceiver.decodedIRData.command==90){
    servo2.write(70);
  }
  else if(IrReceiver.decodedIRData.command==94){
    servo2.write(90);
  }
  else if(IrReceiver.decodedIRData.command==13){
    servo2.write(130);
  } 
}
