What is your sound signal source?
How are you hooking it up to the Arduino?
What are you working with?
Care to mention anything useful at all?
Sorry mate, I am just starting out with arduino.
My signal source would be a speaker. There will be a speaker playing a sound, based on the sound level, LEDs will start working.
I basically connected the peizo to the breadboard directly. I have an arduino mega with a big breadboard.
please let me know if you want anything else.
Something like the attached ought to work . The opamps could be 2 halves of a LM358.
Gain about 30x.
It won’t be quite rail to rail, but should be good enough.
It’s biased such that no signal gives an output at about half the supply, so that peak to peak should betwetween 0ish and +5ish
thank you for the info bro, can you please explain what those do? I have a little problem with what amplifiers do. It would be amazing if you could tell me what to get to get it working.
They use an electret microphone insert, so it has more output and bandwidth than a piezo element.
What frequency range are you wanting to look at?
What is the application?
hello tom thank you for your explanation. I will basically do the same thing as in the video, speaker playing a sound, a sound detector detecting the sound level, like an LED sound visualization, basically a conversion from sound to light. As for the frequency, all I need is to be able to detect sound from an mp3 player (phone), it would be amazing if you could giude me through the parts that I need.
thank you all for your time!
