Hi
Hv created a prototype on a breadboard involving a PIC MCU, a matrix keypad, LCD, buzzer that runs off 3xAA battery. Everytime I turn on the switch, it will display a menu of items which I then select using the keypad.
Quite frequently however, I notice that whenever I turn on the switch, nothing appears on the LCD. I have to turn off and on, sometimes more than once before I see the menu.
Any idea why this is so?
Thks!
