mega32 with internal 1Mhz, with LCD, RTC and 4x3 Keypad.
If keypad's keys are pressed then some actions will take place like toggle of port bits, etc.
Things are wortking fine. but sometime mega32 sense the keypad inputs without being pressed. So LCD shows * chars as it is programmed to accept password.
This mega32 sense 3 times 8char length password and goes in to lock condition, without any keypad entry.
this happnes sometime if a fingure is near to mega32.
what could be the reason.
