Using the 74HC165 shift registers should I wire them for pull-up or pull-down for mmjoy2?
I have read some conflicting information so I am bit confused on 74HC165 & 4021.
The way I currently understand the 74HC165 should be wired is each input pin D0-D7 attached to ground independently with 10k resistors. In line between the input pin and the resistor is a wire connection from a button/switch. The other side of the switch goes directly into 5 volts. The 74HC165 vcc pin 16 should go to 5 volts with a uf 0.1 capacitor branching off to ground, an open to ground it to pin 15 next to it which needs to be grounded anyway for chip enable.
