	Digital Inputs can be used to convey the state of various devices such as push buttons, limit switches, relays, or logic level outputs.		[[File:DAQ1300_0.jpg\|link=\|right\|400px]]
	They have two states: ~~Low~~ and ~~High~~.		Digital Inputs can be used to convey the state of various devices such as push buttons, limit switches, relays, or logic level outputs. They have two states: high and low. Any signal that is expected to interact with more than just these 2 states is inappropriate for this type of input.

	Digital inputs are one of the easiest components to work with, since all that is required is a simple check to see which state they are in when an event triggers.		Digital inputs are one of the easiest components to work with, since all that is required is a simple check to see which state they are in when an event triggers. A digital input can either be ''Active High'' or ''Active Low'':
			*'''Active Low''' digital inputs consider their state to be TRUE when the voltage is low (closer to 0V), and FALSE when high (closer to 5V).
			*'''Active High''' digital inputs are the opposite- TRUE when the voltage is high, and FALSE when the voltage is low.

	~~A digital input can either be '''Active High''' or '''Active Low'''.~~

	~~'''Active Low'''~~ digital ~~inputs consider their state to be TRUE when the voltage is low (closer to 0V), and FALSE when high (closer~~ to ~~5V)~~.		The exact voltage values at which a digital input switches varies from device to device. See the specification table for your Phidget for more details.

	~~'''Active High''' digital inputs are~~ the ~~opposite- TRUE when the voltage is high, and FALSE when the voltage is low~~.
