I'm very new in this Arduino Community, I have to do a pretty complicated project with Arduino (3rd class of high school), which consist to read a 8 - bit number from a dip switch, do the two's complement and finally displays this number to 8 LEDs. I would just like to know how to connect this Dip Switch to the breadboard. Overall, there are 16 digital pins to connect and I have an Arduino UNO which allows 13 digital pins MAX. How to? I could use a Demultiplexer, but I don't know how.
Thanks in advance!
