+# Functions for measuring in Swift Playgrounds "EV3 Animal Rescue" (Miranda)
+
+## Sensors
+
+  * Ultrasonic (cm, inches)
+  * Gyro (angle, rate)
+  * Reset Gyro
+  * Touch (count, on/off)
+  * Light (color, reflection, ambience)
+  * IR (proximity, seek)
+
+## Motor Sensors
+
+* Motor (degrees, rotations, power)
+
+#### Wait for
+
+All sensor methods have a `waitFor` version that waits for the sensor value to be >= or <=. We don't use '=' equality because it is non-sensical for floating point data.
+
+All sensors also have a `waitForIncrease`, `waitForDecrease` version.
+
