  • Page 3: What Is Arduino

    What is Arduino® Arduino is an open-source prototyping platform based on 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.
  • Page 4 Connection Warning! The RXD and TXD are using 3.3 VDC instead of 5 VDC! The connection of the WPM349 to the UNO WPB100 requires a level shifter (WPI410)! Connection table if using a WPMI410 and WPB100: WPM349 WPI410 WPB100 Used WPB100 pins in example below...

    Test Example Connect the WPM349 to the WPI410 and WPB100 as in the table above. 2. Download the tfmini-master.zip file from our website. 3. Open the Arduino ® IDE and load the tfmini-master.zip library. 4. Once the library is loaded, open the BasicReading sketch which is included in the...
  • Page 6 Be sure the baud rate is at 115200 baud! As this baud rate is quite high, try to use short RX/TX wires, otherwise glitches can appear and cause wrong readings. TIP: use the WPM349 in combination with the WPM434 laser module. It makes it easier to find the location where the WPM349 takes the distance.
  • Page 7 Sample Sketch Example code for Benewake TFMini time-of-flight distance sensor. by Peter Jansen (December 11/2017) This example code is in the public domain. This example communicates to the TFMini using a SoftwareSerial port at 115200, while communicating the distance results through the default Arduino hardware serial debug port.
