Move faster a 12V DC motor with L298N

[saintsyt]

Hi everyone, I need help fast.

I have to put a DC 12V motor with Arduino Nano (Old Bootloader), an H bridge L298N and an IR receiver to change the speed with a control, but it is very slow connected to a gear, how do I make the motor go faster?

Here's the code just in case.

//Receptor IR S = D3
//L298N 9=1 white 8=2 brown 10=ENA red
#include<IRremote.h>
int SENSOR = 3;
int enA=10;
int in1=9;
int in2=8;
IRrecv irrecv(SENSOR);
decode_results results;
void setup() {
  pinMode (enA, OUTPUT);
  pinMode (in1, OUTPUT);
  pinMode (in2, OUTPUT);
  digitalWrite(in1, LOW);
  digitalWrite(in2, HIGH);
  Serial.begin(9600);
  irrecv.enableIRIn();
}


void speed3()
{
    digitalWrite(enA, HIGH);
}

void speed2()
{
    analogWrite(enA,170);
}

void speed1()
{
    analogWrite(enA,85);
}

void loop() {
  if (irrecv.decode(&results)) {
    Serial.println(results.value, HEX);
    irrecv.resume();
  }
  if(results.value == 0xC9767F76)
  {
   speed1 ();
  }
  if(results.value == 0xC8155AB1)
  {
   speed2 ();
  }
  if(results.value == 0xB6996DAE)
  {
   speed3 ();
  }
  if(results.value == 0xF32F72D7)
  {
   analogWrite (enA,0);
  }
}

@saintsyt

how do I make the motor go faster?

Use a modern motor driver. The ancient L298 dinosaur wastes about 1/3 of the battery voltage as heat, and it may even be overheating and shutting down.

Pololu has the best selection of modern motor drivers, for example, this one.

Pick a motor driver that can easily handle the start/stall current of your motor.

Hi, @saintsyt

Does your motor speed run fast enough when connected directly to the motors power supply?
What is your motor power supply?

Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.

Thanks.. Tom...
