does one need to use a pull up/down resistor for every PIN used, or is it OK to use one pull-up resistor and connect all the needed PIN's to this one, the same question for the pull-down resistors
for my project I need 8 PIN's to be connected to a pull-down resistor and another 3 PIN's to be connected to a pull-up resistor.
can i work with one resistor for each type i need? or is it better to solder 8 & 3 resistors separatly
the pull-ups are 1K, the pull-downs are 10K
