Description: The Big PIC Clock is based on a PIC16F84 microcontroller (uC.) The software in the uC allows for very accurate timekeeping. For visibility at a distance it uses 2.3"/57mm super large, hi-efficiency red LED displays for the hours and minutes and smaller 0.56" LED displays for the seconds. The circuit incorporates a dimming feature so that at night the reduced ambient light is sensed and the display is dimmed. The software program including a time adjustment mode can control the clock to a few seconds a year. (K73)
