=== Digital sensors ===

[[File:Sensor-Microswitch.svg|frame|left|Microswitch]]

Digital sensors are connected to the red and yellow sockets on the top of the case.
The software can detect if the switch connected between the sockets is open or closed.
Digital sensors are useful for detecting a ‘condition’ such as when a door is open or when a buggy has hit a wall.
The digital sensor inputs can also be used for counting.
For example the rotation of a wheel can be accurately controlled if a microswitch is positioned so that it is closed as the wheel rotates.
