Getting Started
Connect the LaserPING sensor’s pins to power, ground, and
your microcontroller’s I/O pin as shown in the diagram. Note
that the diagram shows the back of the sensor; point the
component side toward your target object.
The LaserPING sensor is supported by BlocklyProp blocks,
Propeller C libraries, and example code for the BASIC Stamp
and Arduino Uno. It is circuit- and code-compatible with
applications for the PING))) Ultrasonic Distance Sensor
(#28015).
