Which pins are which on a shift register? What pins on a 74HC595 shift register are the data, clock, and latch pins?
I just bought an arduino and was trying to do this tutorial https://www.instructables.com/id/Arduino-Expermentation-Kit-How-to-get-Started-wi/step7/8-More-Leds-74HC595-Shift-Register-CIRC05/ . I have hit some trouble though and I am confused when it comes to the shift registers. When he says to connect to the clock pin, do we connect to the SCK (Shift Register Clock Input) or the RCK (Storage Register Clock Input)? When he says to connect to the data pin, do you connect to the SI (Serial Data Input)? Also what does he mean when you say to connect to the latch pin? The data sheet for the Digikey shift register I am using is in the link below.http://www.fairchildsemi.com/ds/MM/MM74HC595.pdf?
