Bidirectional Shift Register (74LS194)

Experiment Log: #1 April 2026. Exploring the universal shift register to create a "right-to-left" extinguishing LED sequence using a 555 timer clock, tried many times to make it work until the very end but it worked out well as it was an ok success, but all and all it was good enough.

MARCH_2026

Decade Counter (1-8 Sequence)

Experiment Log: #2 Designed a counter using 74LS192 and 7447 decoder, powered by an Arduino pulse.. It was a trial and error until the segment display shows the wrong lightings of the number, many errors have been made but it was worth it until it worked perfectly in the end as it counted normally from 1 to 8. I'd say it was a big Success!
