Electrical View of the Shift Register
I thought it might be helpful to take an electrical view of the shift register pins when you’re pressing the…
Shift Register Circuit Build 102
When I was going through and comparing the values I was passing the shift register, I wondered if instead of…
Shift Register Basics – Theory
I think the reason why I love these things so much stems from them being the first IC I ever…
Fun with the 74HC595 and an Arduino
I wanted to quickly post a short sketch that one of the early users put together to play with the…
Bit Masking the 74HC595
In the last module, we went from using massive chunks of code to flip individual bits, to a more elegant…
Bit Shifting the 74HC595
We need to send more than a single bit at a time, and using the previous code would make our…
Bit Banging the 74HC595
Moving bits around with buttons is the introduction to serial communications control, now let’s adapt the techniques we performed manually…
Fundamentals of Serial Communications
In this module we’ll begin working with the very fundamentals of serial communications, using the shift register and buttons on…
