first of all…really thanks for keep helping me… i appreciate it…
and sorry… because actually i face some difficulty to understand your sentence… maybe because of my broken English language… my english not so good… and furthermore u got an abstruse language… so maybe u can just use simple english to me… haha… :laughing: :laughing: :laughing:

okok… I’d tried the code

high P9 pause 1000 low P9

for my BAP carrier… the buzzer will beeping(5V pin9) when applied power and then become LOW(0v pin9) for the rest… thats all…
so… ??? :slight_smile: :slight_smile:

Try putting 5vdc and ground across the speaker / buzzer. (out of circuit)

If it goes click! then its a speaker.

If it goes beeeeeep! it’s a buzzer.

A speaker will make tones like different frequency, like a phones keys, when a wave is sent to it. .

A buzzer will only make the same buzzing sound when dv voltage is applied.

This is what they are trying to understand.

23

ya… i tried it… it goes beep… so it is a buzzer right?? so what u trying to tel me??? im a bit blurr… sorry…
oh ya… bout the bot-board II is using speaker or buzzer actually???

24

Well this helps us understand your problem descriptions much better. You are never hearing beeps from the PROGRAM, cause your transducer makes it’s own sound. To fix the problem you must take out the buzzer and put in a speaker. Then the constant sound will stop. There is nothing wrong with the program, just your HARDWARE. Ok, problem solved… next! lol

25

i need to wait for couple of hours only i can get a speaker… so for now(temporary)… how should i modify my circuit for using my buzzer??? cos i still wanna try using this(same) buzzer…
and actually im so confused… LOL… but i will try figure it out later…
one more question is… that means the Bot Board II is using speaker is it??? is it speaker and buzzer have the same shape same looking?? what is transducer(speaker or buzzer or other else) refer to actually??? if Bot board using buzzer also… then why it can function well but not mine???

:laughing:

26

Else. I think a transducer needs PWM supplied to it to make it go Bzzzzzzzzzzt. A buzzer probably has the PWM built in so only voltage is needed to make it go Bzzzzzzzt.

27

Yes the Bot board II is using a speaker.

I can’t tell you how to make it work… It’s the wrong part!

28

Yup, you’ve got buzzer, not the same as the speaker (transducer) that’s on the BB2.

You should simply turn your buzzer on for different lengths of time

high P9

delay(1000)

low P9

delay(500)

high P9

delay(500)

low P9

Don’t use the sound command with a buzzer, It just confuses me.

to : Jim Frye
i just think of something suddenly…
i shouldn’t asked much on the buzzer/carrier BAP-28
sorry Jim…
but… im new to electronic and im just truly curious on everything… just for academic perspective…
just wanna learn… just for academic perspective…
No offense intended Jim… sorry…
i had bought BBII… but i still wanna learn… just for academic perspective… i mean i care for knowledge…
i don’t know how to express my words (poor English language)… but i assume u understand my words…
