This clock displays the time in binary using discrete LEDs. The use of Flowcode [1] makes it very easy to program the PIC controller in this project. The circuit is very simple and can be constructed with individual parts on a piece of experimenter’s board or using the relevant E-blocks modules: EB006 (1x PIC Multi-programmer), EB004 (3x LEDs), EB005 (1x LCD) en EB007 (1x switches). The firmware, which can be downloaded from the website for this article [2], determines how this circuit functions.
