This is my first post here, so I’m feeling a little, ah, intimidated.
Some background: The last time I dabbled in this field was as a pimply-faced teenager. That was many years (OK, decades) ago - back then prices were in £sd.
As such my questions will seem infantile, but…
With regard to the “TPIC6B595 High Power Shift Register” datasheet at https://cdn-shop.adafruit.com/datasheets/tpic6b595.pdf - in particular the circuit in “9.2 Typical Application”.
What is the purpose of the 0.1uF capacitor?
Welcome to the wonderful world of electronics! 0.1uF capacitors are commonly used to decouple high frequency signals. They are often referred to as a “decoupling capacitor”.
Without them, voltage spikes could disrupt sensitive digital devices (leading to resets / unusual behavior).

Thank you for your reply, the words “decoupling capacitor” were all I required. (Gotta love forums like this and Google!)
My next objective is to understand what datasheets are (trying) to tell me, so expect more dumb questions.
Glad to hear you got it going @Kevin48023!
