For OLEDiUNO Spectrum Analyzer with 3 display modes
After 1 year purchase, I'm not using them more than half year.
My opinions after all that is:
Worth 5 euros but no more.
I'll throw them into the container

Sorry you think this way, but your problem is 100% on your side as my video shows how the display is out when no music is playing.
Of course this is not a professional device which would cost 5 times as much and it is running of a Atmega328 chip mind you.
And, NO, it is not a beta product like you said in an email, I am using original and authentic parts!
On all of my products you can see how they work on various Youtube videos and I sold over 40 of these spectrum analyzer with nobody complaining.
your symptom could even be induced over the power supply or even air as it is over 16.000 Herz.
I tried and did accommodate all your special request and this is the thanks for it?
If you are not satisfied please return it for a refund, I do not want anybody not being happy with any of my products and spreading something bad about them.
I should have known better.
