How to simulate the 74HC165 Shift Register in LabWired

Open the Playground at app.labwired.com and place an MCU board.
Add the 74HC165 Shift Register (catalog type sn74hc165).
Connect VCC and GND to the supply and ground of the board.
Connect CLK and QH to the SPI pins of the board.
Connect SH_LD to the chip-select pin of the board, or to a free GPIO.
Connect D0, D1, D2, D3, D4, D5, D6 and D7 as your circuit needs.
Run the firmware. It selects the part and moves bytes over the simulated SPI bus as on hardware.
