Quick question, I'm using a hall effect sensor (US5881) and I'm wondering if i should connect it to a digital or analog pin on my arduino board.
According to the datasheet, it's either high or low (active), so you would want it on a digital pin . Figure 12.1 shows it with a pullup resistor on the output.
Also, most require a small cap right on the device power terminals, 0.01uF I think.

Datasheet shows 100nF, that's 0.1uF, code 104.
Ok , and I've found they need to be right on the base of the device.
