Sir can we add a password protection before any program to get run ?? I mean any of the operation list within void loop()

[@miliohm]

Sure. Just put while before enter the loop.

[@ashutoshmallik2435]

@@miliohm Ok le me check with this . . . So after while what if we want to add keypad operations again inside the loop after entering in it ???

[@ashutoshmallik2435]

@@miliohm Ya sir while(1); worked very well and password entry occur once and system need to get reset if again need to enter the password , all good . . . Thanks , but now what about this line under void loop()
if(!digitalRead(22))
{
digitalWrite(LED1,HIGH);
}
where should I place it and with what extra script to get these conditions
1) LED glow on button press if the password entered is correct.
2) No action on button press if the password entered is wrong
Please Guide !!!!!!!! Thanks
