Hi
I'm new and I've run into a small problem with recording audio using the TMRh20 library. I decided to try to recreate the project from this page:
The only difference is that I added two buttons for start and end of recording. Both have 1kOhm resistors connected as pull-down.
However, there is a problem. Some files save on SD-CARD incorrectly, in the form of 1kb .wav files that cannot be played back.
Have any of you encountered such a problem?
You can try this instead: How to play WAV audio files with Arduino Uno and MicroSD card - Maks Surguy's blog on Technology Innovation, IoT, Design and Code
I made a talking robot by following this tutorial. Follow all the links given in the blog post to design the amplifier part and prepare your .wav files properly.
Hi. Thanks for your interest in the topic @aliarifat794
The problem is that trying to save a file with recorded audio sometimes breaks down. It saves files as .wav files whose size is 1kb. But they cannot be played back.
This happens maybe 3 times out of 10 recordings saved.
I would like to eliminate this problem in the best way possible, or at least reduce it significantly
