Like most of us, I ran out of output pins once or twice over the years.
At times I just went with a bigger board, like moving from Uno to Mega.
But at times it just didn’t make any sense.
So to solve this, let me introduce you today to the great 8bit shift register
that allow us with the small price of 3 GPIOS to gain at least 8 outputs,
and you can daisy-chain many more.
