An input is something that sends data to a computer. In SAM Space, our input Blocks send data in different forms, e.g. a sensor or pressing a key or a button. There are two types of inputs: True/False inputs and Variable inputs. True/False inputs have only 2 modes: True or False, such as a buttons being pressed or released. Variable inputs can have values that vary between 0-100, such as a Light Sensor that collects different values of brightness. The SAM Space Blocks that are inputs are: Key Press, Button, Light Sensor, Slider, Tilt, Pressure, Proximity, and Heat.
