read from keypad

// read keypad from 1 analog pin ands do something when specific key is pressed
// I tried to re-read inside case, but it's not working

//add this for working
// I add new readkeypad1() function with timeout for re-read from keypad
// after reading the key I compare if not equal to KEY_NOT_PRESSED
// and store the key
