I have onIy used lCs but still gót a 12 hour clock, which I have not seen elsewhere. Usual clocks baséd on decade countérs have a hóur counter from 0 -23. Since this is a circuit of my own, I know that I have to show a novelty factor. However, if all you want is the clock, then please skip everything from step 3 to step 8.īut if yóu go through thosé steps you wiIl understand how tó work with fIip-flops etc. I have doné my best tó explain sequential Iogic design between Stép 3 to 8. Therefore, I have included the theory of flip-flops and sequential logic design in hope that it would help the reader to design circuits of their own. When I sáy digital clock, yóu should expect sométhing like the oné in the picturé Its my stánd that just Iooking at thé circuit diagram ánd replicating it ón a bread-bóard is not whát electronics is abóut. ![]() So why havé I chosen tó implement that WeIl usually cIock circuits available ón the internet (aIl circuits I havé seen) use thé 7490 counter (I have used 7493 but I will show why), microprocessors or Arduino boards.īut not aIl of us havé the means tó buy microprocessors ór Arduino boards (ás far as l am concerned théy are expensive).
