Very glad to hear! Send me the link if you ever upload a video using it, will love to watch it

How to creat?

@@MrAkpla Here it is: kzfaq.info/get/bejne/qKt6hZyJydWdZoE.html

can you help me im having some issues my midi see when i blow in but nothing happens ? can can you please send me some instruction? thank you in advance

I would like watching your project.

Sure but you would still need something to control the pitch of the sampled instrument. Maybe you could perform volume + pitch detection from a microphone and use this as input.

@@MrAkpla Yes. the idea would be to play in two people one with a real saxophone acoustic instrument and the other with a control keyboard, with saxophone tones to play in pairs or trumpet and trombone the idea of the volume controller would be just to control the sample volume to play in pairs only for more real partners.

Andreas Marco Haven't looked into it but I'm 90% sure you can by hooking some midi module or cable to the arduino. You wouldn't even need to worry about flashing the serial chip if done that way.

Thank you for the reply. I actually have a Yamaha VL-70-M, which has a breath-controller input and it could be interesting to use a breath-controller with it to get use of its full potential.

MIDI out from an arduino is really easy, you find the circuit in this tutorial, www.arduino.cc/en/Tutorial/Midi it's just two resistors and it works with the same code

Hi! Thank you very much. The detailed schematics of the decoupling circuit is on page 5 of the sensor datasheet linked in the description (figure 3) but as I state in the video I wouldn't bother assembling it and just hook up the sensor and the pins on the pcb. Midi protocol is only 7 bits, that is a resolution too low for the decoupling circuit to make any difference.

Hi, if its range goes from 0 to 40kPa (assuming that from the part name) I'm afraid it's not going to be precise enough for this task. Can't you get the one on the video shipped from RS-online?

@@MrAkpla hi thanx for the real quick response i will try it again thank you very much

I had used MPX5010GP with only 10kPa max pressure, and was not able to blow out the whole range. (only about ~800 of 1024 in arduino reading numbers). It is even with all air going directly to sensor, without any leak, and it was hurting my ears. Maybe a pro trumpet player has more mighty lungs, but I do not think blowing so hard into a sealed up pipe worth it, and I believe that 10kPa is an absolute maxium you may need here, and is already an overkill. 6kPa that MrAkpla had used covers all the actually usable range, and probably is even better choice than my sensor. Also if you use only part of the range - you loose resolution, Therefore, I do not think that using 40kPa sensor would be a good idea. (roughly, if you blow only 5kPa from a 40kPa sensor, you will have readings from 1 to 255, getting 4 times worse accuracy, compared to 5kPa sensor that will give you 1-1024 range of readings. In reality it is going to be even worse) Sorry for necroposting)

hocam ne yaptın sende vazgecenlerdenmısın :)((

Thank you :) Unfortunately it won't work with a Nano as its USB-to-serial chip isn't compatible with Hiduino, Nano never comes with an atmega 8u2/16u2

Thanks. I've got it working with a Nano and serial->MIDI bridge (Hairless MIDI) for a bit of fun. I've just got a Teensy 3.2 so I might try it on that.

robman80808 Well yes, that's an option, I did use hairless midi when prototyping but the degree of usability isn't nearly as high. With hairless midi bridge it's not plug-and-play as it is with hiduino and the multiple software layers add to the latency.

robman80808 hey buddy, an Arduino Pro Micro or a Leonardo would work, with a bit of editing of the code. The ATMega32u4 chips used on those boards can be recognised as a HID device natively.

No, this particular one doesn't work with negative pressure

@@MrAkpla How are you going to be able to reproduce this then?: kzfaq.info/get/bejne/ea5nfaWYrq67mqc.html

16U2 or 8U2 chip. You can check more details in the project page I have in hackaday hackaday.io/project/161678/components

If the PSI more or less matches the human range and the form factor is good for using it with a hose, I don't think there would be any problem.

🤣🤣🤣🤣

Good question hehehe

I had my leonardo kept outside in rain somehow ... and it's still working perfect -_- I got my Uno dirty from mice excreta and washed it with detergent and it works just perfectly

Thank you :) Well if I had to make you one I'd have to make some orders to China, and it would take for it to arrive up to two months. I could buy a new melodica hose/mouthpiece for hygienic reasons and send you my breath controller and then build another one for myself, but for it being effort-worthy I'd have to charge you around 100 euros + shipping, if you're up to it we have a deal. But to be honest I'm not trying to make a business on it but to teach everyone how they can make one at their homes for cheap. You can buy a commercial breath controller (tecontroll's) sold for 120€ + shipping and you'll probably be better off with that than with mine.

Voltage of a capacitor means the maximum allowed voltage applied to the capacitor. If one doesn't know the basics of electrical components and basics of electronics one shouldn't play around with it. However, go free with the lowest values from your list.

HI, Where do the pins from the sensor connect on the analog inputs of the board? A1, A2,...? Thanks! Awesome project!!
