want help with player controls project please

hiya, i am currently at college learning engineering. i want to find out the details behind play,stop,fast forward etc buttons..and how they work with a mp3 player because i have looked on google etc and found nothing. if anyone can help it would be greatly appreciated.

The switch works by connecting two pads/conductors on the PCB or inside a microswitch. For a PCB switch, often a small metal dome with an indent is placed over the pads so that there is a tactile response when the button is pressed.

If you're wondering how the buttons actually start/stop/pause the MP3 music however, you'll find that they don't - the state of the switch (i.e. ON or OFF) is read by the MP3 controller (an IC), which can control how the music is played/stopped/paused/etc.

thanks alot dougy83

where did you find that info btw?

In my head. Open up a few scrap devices and you'll see for yourself.

sheesh. It takes patience replying to that eh, Doug..
