Nice stuff, but not exactly what i'm looking for :D Thank you gfvalvo! This will be perfect!!!

I'm wondering if exists any component of this kind. I'm trying to build a very compact interface for an handeld application of teensy + mini oled screen (something to wear on wrist) and i'm looking for a potentiometer-like control which can work also like a push button... can someone help me in...

Thank you very much for your answer Michael!!!

Hi, I need to power my Teensy 3.2 with a battery, but i don't know what kind of battery use, and how to connect it to Teensy? Anyone can help me? :confused:

Italy... I see that Arduino.cc sell here but they have only 4 Teensy in stock at the moment (and i don't see any discount policy for big order)

A question for Paul and "the team"...what if i want buy a large number on Teensy 3.2? What if i want buy 25/50 Teensy 3.2? There is some discount for big order? :rolleyes:

Ok, I'll try also the 13th and 14th port. Just for my information... what does it mean that "they all use ADC0"? :confused::confused:

What if i change ADC port for my keyboard? (like ADC4)... analogRead(4)? :confused:

Not sure if it's the right section of the forum. :confused: I had a problem using AudioLibrary and Nokia 5510 LCD monitor together... :( As I stated here now i'm able to detect the main frequency with probability percentage! Great! :cool: The next step of my project is to show these data on a...

I'll be back on the forum after a few weeks . I bought a Teensy 3.2 and I watched the video " Teensy Audio Tutorial " , but I still have some doubts about how to get what I'm trying to do for several weeks ( yes, I know ... shame on me ; ) ) What I'm trying to do is to get the frequency of a...

I've watched the tutorial video and i've tried also the design tool (which is really brilliant!!!), but... i can't understand if I have any chance to apply "notefreq" in 400-800Hz, since i understand that fft has a resolution that can't afford what i'm trying to do (43Hxz resolution of fft2014...

I'll study it and I'll be back for the [RESOLVED] tag ;) Thank you Lord Paul ;) A last question about supported hardware... here https://www.pjrc.com/teensy/td_libs_Audio.html i can't see Teensy 3.2... it's a lack of update or i have to buy a Teensy 3.1?

Thank you duff, but i'm looking for the possibility to apply FFT (or YIN) in realtime, acquiring the signal with a mic and returning the main frequency, just like a guitar tuner does. These examples show an YIN application on a recorded sound, am I right?

Hi, i'm trying to build a tone detector which is able to detect main frequency in an audio signal acquired by an amplified mic (20db) on Arduino/Teensy. This is the mic -> http://electropit.com/index.php/2015/12/20/fc-109-max9812-microphone-amplifier-module/ Since the range i'm inspecting is...
