PicoTOF

This project uses a Raspberry Pi Pico to interface with the Adafruit VL53L1X Time of flight sensor module. Measurements are displayed on a SSD1306-based OLED Display. The code is written for the Arduino IDE. Please see Pi Pico Time-of-Flight Project in Arduino IDE for a complete walk-through of the project.

Hardware

• Raspberry Pi Pico DigiKey
• Adafruit VL53L1X Time of flight sensor module Adafruit
• 0.91 inch, 128x32 pixel OLED monochrome display Amazon

Circuit

The VL53L1X sensor module and SSD1306 display are connected via I2C. A momentary pushbutton on one GPIO pin cycles through the display modes. See link above and code for more specific description.
