Digital inputs can be the simplest transducers. Such as switches. there are two possible states that digital input can be. On or Off. The switch is the most common example, but simple concepts can lead to creative outcomes!
For example, if you wanted say, a light to come on when your cat lies down on the door mat, the process is a simple switch circuit. When the cat lies down, the weight is applied to the switch, which may be under the mat. When the weight is applied, the switch closes, and the circuit is complete, therefore creating resulting in the event, (in this case the light coming on). However applying this process on a slightly grander scale will be interesting.
Note; Momentary = switch's that have a spring to re-adjust back to an 'Open' (non complete circuit) position.
Toggle switches do not have the spring and are stay in the position they were left in.
