BIG PIC Clock Kit – K73
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. DIY Kit 73
The circuit incorporates a dimming feature so that at night the reduced ambient light is sensed and the display is dimmed. Before we construct the clock please read through the following theory about clock adjustment and setting and the general circuit description.
Software. Both the commented source code and the object code are available for download from our website. http://kitsrus.com/soft.html/clocksrus.zip
