Can you use it with high volume buzzer like 12v

[@mohda5894]

How to set the buzzer ringing for a few minutes?

[@MaazKhan-io4et]

Awsome bro

[@janaidi630]

Can i use buzzer 5v.??thanks

[@snnyhacksci.5984]

Yes, but use 4V to 5V volt power supply. For example, you can use 3 x AA battery.

[@janaidi630]

@@snnyhacksci.5984 Thanks..🙏👍

[@somarcire2688]

Can you give me the voltage of piezo buzzer that you put? Because I have 3v-24volt only..is it okay? Thanks

[@snnyhacksci.5984]

You can use 3v-24v piezo buzzer. .Thanks

[@inzamam3526]

Can I connect led on the places of buzzer

[@snnyhacksci.5984]

Yes, with a current limiting resistor
