just bought this button. https://www.adafruit.com/product/481
I want to connect it to my Gemma.
I want the light to be permanently on.
From what I understand to make the light be permanently on I need to connect: - (negative) of button to Ground of my Gemma (I already have something connected on the ground. Is it ok to connect 2 cables at the same time?) + (positive) of button to 3v of My Gemma
Now to receive data input from the button I need to connect: C1 of button to D1 input of my Gemma NO1 of button to D1 input of my Gemma (or NC1 to D1)
I ll also need use the INPUT_PULLUP command from what I understand.
Is that correct? It looks logical to me, but I've read many responses on forums for similar questions and no one has done it like that.
