Using an IR remote with the L293D motor control shield

Hi, I was wondering how I can use an IR receiver to control the L293D motor control shield

Thank You, cubingmaster10233

You can do so by adding IR Receiver module and then getting IR remote code and adding that code in case and in case your action that if you press the button what to do.

Here is the small code for your help

#include <IRremote.h>
#include <AFMotor.h>

AF_DCMotor motor1(1);
IRrecv irrecv(2);
decode_results results;

void setup()
{
  Serial.begin(9600);
  motor1.setSpeed(255);
  irrecv.enableIRIn();
}

void loop()
{
  if (irrecv.decode(&results))
  {
    switch(results.value)
    {
      case 0xFF30CF:
        // Code for button "1" on the IR remote
        motor1.run(FORWARD);
        break;
      case 0xFF18E7:
        // Code for button "2" on the IR remote
        motor1.run(BACKWARD);
        break;
      case

Thanks, But the code had this error message:

Kindly check the following:-
Do you install all the liabries which are required
Have you changed the things as you want

Try this update code

#include <IRremote.h>
#include <AFMotor.h>

AF_DCMotor motor1(1);
IRrecv irrecv(2);
decode_results results;

void setup()
{
  Serial.begin(9600);
  motor1.setSpeed(255);
  irrecv.enableIRIn();
}

void loop()
{
  if (irrecv.decode(&results))
  {
    switch(results.value)
    {
      case 0xFF30CF:
        // Code for button "1" on the IR remote
        motor1.run(FORWARD);
        break;
      case 0xFF18E7:
        // Code for button "2" on the IR remote
        motor1.run(BACKWARD);
        break;
      case
    }
  }
}

The code still doesn't work. The code is:

#include <AFMotor.h>

AF_DCMotor motor1(1);
IRrecv irrecv(2);
decode_results results;

void setup()
{
  Serial.begin(9600);
  motor1.setSpeed(255);
  irrecv.enableIRIn();
}

void loop()
{
  if (irrecv.decode(&results))
  {
    switch(results.value)
    {
      case 0xFF30CF:
        // Code for button "1" on the IR remote
        motor1.run(FORWARD);
        break;
      case 0xFF18E7:
        // Code for button "2" on the IR remote
        motor1.run(BACKWARD);
        break;
      case
    }
  }
}

And the error message is:

     }

exit status 1

Compilation error: expected primary-expression before '}' token

Thanks

This is just example code you have to change it as per your requirement
Also it is not possible to guide you properly without your code, circuit diagram, and project use
