By using Arduino serial monitoring,sensor gives data in digital output format.I just want to convert this digital output into sound output thus i can listen sound via microphone.Is there any way out to solve this problem.Please provide me the instruction.Here i attached my output file.
Thank you.
If you are using Python you can look into https://docs.python.org/2/library/wave.html
Hello, Asif,
You can do that using Matlab, for example. Please find attached a script.
You take your values and put them in an Excel file. The first values look strange so I removed them. Please find attached the processed .xls file. All the others look like binary values. Then use Matlab to read the values, process them a little and you can hear the signal.
Also, audio signals are recorded using a microphone. For playing, you might want to consider a speaker.
Kind regards,
Robert
If you like challenges:
- Start with researching the .wav format.
- Then write a software that's converting your serial log to the .wav format.
But don't expect to hear much: the log file you provided has only variations in 4 out of 9 bits. This won't make for much sound experience. (BTW: where is the 10th Bit?)
Robert Alexandru Dobre I also had the same query and I used your code. I wanted to ask you, when we plot this data, what to the coordinate axis represent? Is it amplitude vs time?
