@@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 !!!!!!!!
