I have a machine that uses a 3 thumbwheel switches to provide operation settings, each switch has 4 outputs and a common. I want to to control who can change the settings by using am ID card reader that provides an output.
my thought is if I add a 8-bit register (here or similar option.) to store the values and update only when the ID card is swiped.
so 4-bits => register on signal from card reader to reset and and store new values
what kind of input do I need on the CLK?
This is my first time using registers and was wondering if anyone has any insights or see any flaws in my approach to this.
