Great ! I am working on using EEPROM to shift its data to 40 LEDS and this video helps a lot THNX

The whole loop thing to read bits from the register can be simplified by using arduino integrated function: shiftIn(dataPin, ClockPin, LSBFIRST)

Thanks for the video, anyway I wish if you make a video about the difference between 74165 and 74166

Dear Sir, Are 74HC165 and 74LS165 equivalents in every aspect of functionality ??

for STM32 possible?
