Comment correction Circuit 14 line 172

Hi,

I am just getting back into the coding game after a long absence, but looking at the code description for shiftWrite and referring to the datasheet for the HC595 I think the latching description below is incorrect - by my understanding of the datasheet, the latch actually activates on the low-to-high transition rather than the high-to-low. Am I correct?

// Once the data is in the shift register, we still need to
// make it appear at the outputs. We'll toggle the state of
// the latchPin, which will signal the shift register to "latch"
// the data to the outputs. (Latch activates on the high-to
// -low transition).

Thank you for your time.

Thanks for catching that! The clock pin is actually the high-to-low transition while you are correct that it the latch pin transitions from low-to-high.
