**1.Description**

 In this project, we will work to control the car using an IR remote control.

**3.Test Code**

```
#include <MecanumCar_v2.h>
mecanumCar mecanumCar(3, 2);  //sda-->D3,scl-->D2
#include <IRremote.h>
/****Introduce the infrared remote control header file***/

int RECV_PIN = A3;
IRrecv irrecv(RECV_PIN);
decode_results results;

void setup()
{
  Serial.begin(9600); //Set baud rate to 9600
  mecanumCar.Init(); //Initialize the seven-color LED and motor drive
  irrecv.enableIRIn(); 
}

void loop() {
  if (irrecv.decode(&results)) {
    Serial.println(results.value, HEX);
    switch (results.value)
    {
      case 0xFF02FD: mecanumCar.Stop();       break;  //Stop
      case 0xFF629D: mecanumCar.Advance();    break;  //Advance
      case 0xFFA857: mecanumCar.Back();       break;  //Move back
      case 0xFF22DD: mecanumCar.Turn_Left();  break;  //Turn left
      case 0xFFC23D: mecanumCar.Turn_Right(); break;  //Turn right
    }
    irrecv.resume(); // Receive the next value
  }
}
```

**4.Test Result**

After uploading the test code and turning the DIP switch to the ON end and powering up. When we press the button ![](media/image-20251031161442170.png)on the remote control, the car moves forward, then ![](media/image-20251031161519495.png),,the car turns left,![](media/image-20251031161707391.png),the car moves back,![](media/image-20251031161747116.png),the car turns right,![](media/image-20251031161816571.png),the car stops.
