“A laser harp is an electronic instrument that lets you “pluck” laser beams like a harp to play notes. In this guide, you’ll learn how to build your own version of a laser harp using a Feather M4 Express …
Content for VL53L4CD
Specifically designed for proximity and short-range measurements, the VL53L4CD provides very accurate distance measurements from only 1 mm up to 1300 mm. A new generation laser emitter with 18° FoV improves performances under ambient light, with ranging speed up to 100 Hz. With very low power consumption thanks to an autonomous mode with programmable distance threshold, the VL53L4CD is ideal for use in battery-powered devices. Its fully embedded on-chip processing helps to reduce design complexity as well as BOM cost since less powerful and less expensive microcontrollers can be used. Like all Time-of-Flight (ToF) sensors based on ST's FlightSense technology, the VL53L4CD records an absolute distance measurement regardless of the target color and reflectance.
