Putting 4 vibration motors together

Projects Programming
1

Hi guys,

I am really new at arduino programming. Doing a project and want to control 4 vibration motors from one arduino (pins 3;4;5;6;). Is it possible using this code ? and how to multiply it ?

const int motorPin = 3; 

  void setup()
  {
  pinMode (motorPin, OUTPUT) ;
  }
  
  void loop()
  {
    digitalWrite (motorPin, HIGH) ; 
    delay(1000) ; 
    digitalWrite (motorPin, LOW) ; 
    delay(1000) ; 
  }

First you need to understand how to get rid of the delay() calls and replace them with non-blocking timing.

It might sound complicated.
In fact it's a commonly used pattern.
There's a nice example included in the IDE. IIRC it's called Blink without delay.

Also make extensive use of the auto-indent feature of the Arduino IDE. Indentation makes code clearer and bugs less likely :slight_smile:

const int motorPin = 3; 

void setup()
{
    pinMode (motorPin, OUTPUT) ;
}
  
void loop()
{
    digitalWrite (motorPin, HIGH) ; 
    delay(1000) ; 
    digitalWrite (motorPin, LOW) ; 
    delay(1000) ; 
}

Is it possible using this code ?

No. You need to add a lot more code.

and how to multiply it ?

Use arrays and for loops to "multiply" it.
