i have stated project and it seems to go ok till now.
I have an arduino mega with 27 physical buttons and a web server on an sdcard.
When someone pushes a button the corresponding icon in the web page changes state.
How can i add a wav or mp3 “beep” sound on the html page to play when someone pushes a physical button?
In the attachments you can find my arduino code and html page.
