Example Code for Arduino-Read data by polling

Hardware Preparation

• 1 x Arduino UNO control board
• 1 x ToF laser ranging sensor
• Several Dupont lines

Software Preparation

• Arduino IDE, click to download Arduino IDE
• Download and install the VL6180 Library and Sample Codes. (About how to install the library?)

Wiring Diagram

Other Preparation Work

• Modify I2C address (invalid after power off)
• Initialize serial port at 9600 baud
• Initialize VL6180X sensor
• (Optional) Change I2C address using VL6180X.setIICAddr(0×29)
