I want to do an extension for an Arduino Nano pin.
I have 8 buttons. 74HC595's outputs are related to each button:
- Button 1 corresponds to pin 0 of 74HC595;
. - Button 8 corresponds to pin 7 of 74HC595.
By pressing one of the buttons, change the status of 74HC595 for leaving without affecting the status of other outputs.
An example, or an address is welcome.
