4. What is Arduino ®
Arduino ® is an open-source prototyping platform based in easy-to-use hardware and software.
Arduino ® boards are able to read inputs – light-on sensor, a finger on a button or a Twitter
message – and turn it into an output – activating of a motor, turning on an LED, publishing
something online. You can tell your board what to do by sending a set of instructions to the
microcontroller on the board. To do so, you use the Arduino programming language (based on
Wiring) and the Arduino
® software IDE (based on Processing).

5. Overview
General
This product is based on ToF (Time of Flight) principle and integrates unique optical and
electrical designs, so as to achieve stable, precise, high sensitivity and high-speed distance
detection.
ToF ’s operating principle is as follows: a modulated near-infrared light is sent from the sensor
and reflected by an object; the distance to the object to be shot can be converted with the
sensor by calculating the time difference or phase difference between the light sending and the
light reflection, so as to produce the depth information.
6. Connection
Warning! The RXD and TXD are using 3.3 VDC instead of 5 VDC!
The connection of the VMA349 to the UNO VMA100 requires a level shifter (VMA410)!
