Hi All,
I'm just getting started with the Arduino and electronics in general. I have a suggestion for clarifying the text of the button tutorial, as it confused me a bit the first time through. The original text describing the wiring is as follows:
We connect three wires to the Arduino board. The first goes from one leg of the pushbutton through a pull-up resistor (here 2.2KOhms) to the 5 volt supply. The second goes from the corresponding leg of the pushbutton to ground. The third connects to a digital i/o pin (here pin 7) which reads the button's state.
My suggestion is as follows:
We connect three wires to the Arduino board. The first wire goes from [glow]the first leg[/glow] of the pushbutton through a pull-up resistor (here 2.2KOhms) to the 5 volt supply. The second goes from the [glow]other[/glow] leg of the pushbutton to ground. The third connects to a digital i/o pin (here pin 7) [glow]to the first leg of the pushbutton,[/glow] which reads the button's state.
Thanks!
