Hi everyone... I'm now working my intergrated audio system (PC in/MP3 player in/iPod Dock in/Fm Radio in) now i'm thinking rather than using normal rotary type of selector switch, why i'm not trying to use PIC + LCD screen as selector switch? Now here's plan there are 4 button and relay. 1 -FM Radio 2 -PC in 3 -iPod Dock 4 -MP3 player there also 1 16X2 LCD + PIC When button 'fm radio' pressed relay 1 toggled where the input radio goes to output- LCD displyed (FM RADIO) When button 'pc In' pressed relay 2 toggled where the input pc in goes to output- LCD displayed (PC in) When button 'ipod' pressed relay 3 toggled where the input ipod dock goes to output- LCD displayed (iPod Dock) When button 'MP3' pressed relay 4 toggled where the input mp3 in goes to output- LCD displayed (MP3 Player) from the output > as usual > pre-amp and POwer amp (TDA 7294)http://www.diyaudio.com/forums/images/smilies/biggrin.gif So now, anyone here has experienced using PIC to control the amplifier?? OR any web links that explaining more about controling amplifier using PIC.. http://www.diyaudio.com/forums/images/smilies/confused.gif then my NEXT idea is controling pre-amplifier using PIC (VOL/BASS/TREBEL) then if working well the next step is interfacing the PIC to IR remote to control the whole system....http://www.diyaudio.com/forums/images/smilies/rolleyes.gif This may be NEW idea for DIYing your amplifier.. Thanks for helping...
