Hi guys,
I would be grateful if someone could help me out.
I have a code which runs one led along with 2 buttons and a dfplayer.
The dfplayer starts with a sound and one led, which blinks and stays on.
I wanted to add 4 more leds to do the same.
I been rattling my brain trying to work this out. Could someone help me out.
Thanks for any help given
Post your Code and i will see if i can help.
Sorry I am unable to insert this into the code box. Maybe I am using my mobile that’s why
I can’t get the box to open.
Here is the code.. sorry again for the way I am adding it.

You should just be able to add more leds pins and then call them whenever you want. You have "int ledPin =5" already. Add more like
//Code:
ledPin = 5
ledPin2 = 6
ledPin3 = 7 /////or corrasponding pins you want to turn on
//Code End:
Then make sure you tell pinMode which pins are input or output like this
//Code:
pinMode(ledPin, OUTPUT);
pinMode(ledPin2 ,OUTPUT);
pinMode(ledPin3, OUTPUT);
//Code End:
Then anytime you you turn on the led with digital or analog write call whichever led you want like this.
//Code:
if(something)
digitalWrite(ledpin2, HIGH);
Code End:
Can you be a bit more specific as to what you want the extra LEDs to do? Just the same as the one already connected or some other magic?
I have tried adding more ledpin it keeps showing error.
I want the lED to do the same as the
One already connected. And that will be magic
All Arduinos are innoculated against luck and magic before they leave the factory.
kamz007:
I have tried adding more ledpin it keeps showing error.
And yet you decided not to show neither the code, nor the errors.
Were you looking for help, or just to bump your post count?
Show what you tried (and use code tags as explained).
Post the error message that get (complete, there is a button to copy it in the IDE) so we can explain which errors you made.
this is the code I am using. it uploads to the board but only ledpin 5 only works. I am trying to get all the leds to work the same as ledpin 5

but only ledpin 5 only works
Could that be because it is the only pin you ever write to?
