Daisy Chain Example

[Chao8219]

Hi, Dear All,

I am wondering if more examples of daisy chain 74HC595 are needed. The PR #17 is straight-forward, but no examples are given.

The test I have is based on one ItsyBitsy M0, one level shifter 74AHCT125, two 74HC595, one 10 Segment Light Bar.

I also did a Fritzing diagram to show wiring.

Just let me know your thoughts. Thanks!

Best,
Chao
