Hi all,
I'm totally new to this hobby, so please forgive me if my question is too stupid...
If I wan't to use a shift register similarly as below how can i make sure that the current through the chip isn't too large? Is there some internal resistance for the input pins? If I connect a +5V battery to the +5V and flip the switch then, without a resistance, the current would be very large, no?
I hope my question makes sense and you can help me out.
Thanks!
