Switch monitor Project

-

 hello,

i'm using adafruit metro mini 328 board.  i'm monitoring status of switch on truck , sending outputs device when switch has been turned on.

my issue truck has been giving false "on" , false "off".  think there interference on line i'm monitoring. when switch off must getting voltage spikes causing board think switch has been turned on, once goes away switches off.

i've added delay , state detection in , it's helped still doesn't seem solved problem. i'm hoping can check out code , make suggestions improve way i'm doing this.

find code attached. in advance @ all!

if put every { on line itself, used tools + auto format, , removed of useless white space, code far easier read.

you read switch many 3 times, , save "current" state last state. of 3 reads "current" state?

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
