what does:
goes function , changes value of array 1 (on) 0 (off) , resets on when leave function , return it.

what needs do:
not reset function. want able push button 1 , turn off 2 or 3 or whatever leds , go main menu , push button 2 , same return button , and turn rest of lights off. need on once need able pick , choose lights shut off.

also know isnt correct syntax arduino once on command line can make work arduino.

thanks-

hi,

it not clear me, wynt program do. think 1 problem is, declare lcal arays led1[], led2[] inside function. if leave function , reenter later on, array created new , initialized 1. try decalre arrays befor fucntion button1 global variables:

int led1[5] = {1,1,1,1,1};
int led2[5] = {1,1,1,1,1};
...

int button1 ()
{
...

mike
