I have a question regarding “Arduino A Quick-Start Guide, Second Edition”
On page page 49, the first paragraph, the last sentence, it reads:
“Make sure the pushbutton’s orientation is right. Its connected pins have to bridge the gap of the breadboard”
If the pins on the two left side, and likewise for the 2 pins on the right side as you look at the picture in the book, are connected, why do they have to bridge the gap? Since those two pins are connected, it seems that the button could have been constructed with only one pin on each side.
