Hello, I am lost. I got the SparkFun Shift Register Breakout - 74HC595 and tried to follow the tutorial at https://learn.sparkfun.com/tutorials/sh … 1610730333. Unfortunately, the tutorial uses the 74HC195, and the labels are completely different.
Tutorial: Clock CLK, Clock Enable CE, Connect shift/load SH/LD.
74HC595: L_Clock, Clock, OE, Reset.
It is unclear to me how to wire this up, since on the only one can identify is Clock. Further, is the code provided supposed to work with this chip?
Hello Tom.
It looks like our guide really only covers the 74HC165 rather than the 74HC595 that you have. I could have sworn we had a guide for the 595 but I’m not able to locate it right now.
Here’s what I’d recommend until we can sort out our tutorial.
Use this guide:
https://lastminuteengineers.com/74hc595 … -tutorial/
But connect the breakout board as follows:
Breakout — Arduino
SER_IN — D4
L_CLOCK — D5
Clock — D6
/OE — GND
/Reset — +5V
GND — GND
VCC — +5V
This photo should help too. 
Got it! Thank you, works now
