Help to wire something

Hello everyone, hope your all having a great day. So I'm doing a science project and k need to make a electric quiz board( of you don't know it's easier to just google it). So I have to add a led which is mandatory. But you can get bonus marks if you add extra stuff like buzzers etc. I added a active buzzer and it worked fine. And then I tried the passive buzzer but it's hard to work with because the led stays on all the time or follows the buzzers pattern or only the buzzer works and not the led. Can you guys help me wire it? Thanks in advance.

. Can you guys help me wire it?

Well we need to see how you have wired it already then we can tell you where you went wrong with your homework. Otherwise just giving you the wiring is like cheating on your homework by doing it for you.

So post a schematic and post your code because it is more likely that your code is the problem.

Linkuru: just google it

You have some fundamental misunderstanding of how Google works. My Google is not your Google. It knows where I am and what I have searched in the past. There are different advertisers who want to sell me different things to what they want to sell to you. It will give me different results. Please just tell us what it is or give a direct link to a page with a simple photo or explanation. Wikipedia is good for that.

Without a schematic of what you have wired, it is impossible to help. And there is a problem with the code you didn't post. (I didn't post the description of the problem.)

#include "pitches.h"

// notes in the melody:
int melody[] = {
NOTE_C4, NOTE_G3, NOTE_G3, NOTE_A3, NOTE_G3, 0, NOTE_B3, NOTE_C4
};

// note durations: 4 = quarter note, 8 = eighth note, etc.:
int noteDurations[] = {
4, 8, 8, 4, 4, 4, 4, 4
};

void setup() {
// iterate over the notes of the melody:
pinMode(8, OUTPUT);
  pinMode(7, OUTPUT);
    digitalWrite(7, HIGH);
}

void loop() {
  for (int thisNote = 0; thisNote < 8; thisNote++) {

  // to calculate the note duration, take one second divided by the note type.
  //e.g. quarter note = 1000 / 4, eighth note = 1000/8, etc.
  int noteDuration = 1000 / noteDurations[thisNote];
  tone(8, melody[thisNote], noteDuration);

  // to distinguish the notes, set a minimum time between them.
  // the note's duration + 30% seems to work well:
  int pauseBetweenNotes = noteDuration * 1.30;
  delay(pauseBetweenNotes);
  // stop the tone playing:
  noTone(8);
}
}

the code is this one

and the pitches.h code is

Sorry about that I didn't know that's what your supposed to do.

I’ve used that example code in the past. If you followed the instructions, it’s pretty hard to get wrong. The example is intended to drive a simple speaker from the chosen output pin (possibly amplified through a transistor).

It won’t work with most ‘buzzers’ as they require a different drive method - and often generate the tone within the buzzer.

You may be able to find an instructable (urgh!) that uses a similar method - which will help you get the basics working.

All that sketch does, is shake the output pin at various frequencies (with the tone() ) function. The speaker turns those voltage changes into sound you can hear,

What do you mean instructables?

Back to Google again.

Linkuru: What do you mean instructables?

Instructable is a crap web site where idiots post stuff. However if you know more than the idiots you might pick up some good ideas but never try to learn fundamental stuff from it.

Oh ok. But regarding the schematic can I give you a picture?

Post #7 tells you everything you need. If you can’t get past that, i’m sorry but you need to go back a few steps, and practice with the very basics, blinking LED etc...

Instructables certainly isn’t the font of all knowledge, but if you know nothing, it can help you gain some understanding of simple concepts - then run away from it as fast as you can!

Can you explain why the circuit works with a normal buzzer but when I add a passive buzzer the led is dimmer and follows the tone of the buzzer? Is it because their is not enough power?

Ok so it's done and it worked. I didn't change the code either. So basically I added a nte2321. And that solves the problem. And now the light bulb will stay on solid and the buzzer will follow the code.

Yay! Good perseverance - I hope you learned a lot.

Cheers! Sorry for being terse, but you did it yourself!
