B4R Question Shift Register 74HC595 Problem

[tzfpg]

I used WeMos D1 R2 but i facing not enough output. I decide to use shift register (74HC595)
but my WeMos D1 R2 left only 2 output.

Can I using this two output to communicate with shift register to make 4 output?

T4HC595 needs three pins. You should free one more pin (move it to the Register's output).
