Constant audio input

-

hi,

is possible arduino listen audio input, , if there no sound more 5 sec move servo.
i new arduino , if give me reference of similar, grateful.

quote
i new arduino
do have electronics or programming experience?

i suggest start reading through arduino language reference.   if you've programmed before should make sense.   if you've never programmed before won't understand all, it's not lot read-through , give idea of can do.

then read-through of example programs , maybe try few of them.  

i'm assuming line-level audio signal?    the analog read serial example shows how read analog voltage.  then it's if-statement, timing, , servo library.

there's 1 more thing...   arduino can damaged negative voltages (or voltages greater +5v).   need protection circuit protect against negative half of ac audio signal.

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
