I am not very good at understanding current, so I was hoping someone could help calrify the difference between pulling up multiple digital IC pins to
Vdd with either a single resistor OR one resistor per pin?
if you are connecting multiple pins to the same resistor, would you just use a higher value resistor? Ie. instead of 4
10k resistors connected to
Vdd, pull-up everything with one
40k resistor? Or perhaps the other way around?
