The four most important parameters are pin, type, rate and direction. The four most important parameters are *pin*, *type*, *rate* and *direction*.
The rate defines how many times per second you want to poll that The *rate* defines how many times per second you want to poll that
sensor. For example, a voltage sensor might only be polled once a sensor. For example, a voltage sensor might only be polled once a
second (or even once every 2 seconds: rate=0.5), whereas a sonar second (or even once every 2 seconds: rate=0.5), whereas a sonar
