RP2040-Zero Powered Laser Range Finder with GUI and a 2.4" TFT Display

[hesam.moshiri]

In this article/video, I used an RP2040 Zero board, a VL53L0X Laser time-of-flight ranging sensor, and a 2.4” TFT display to build a graphical laser rangefinder unit that can be used to monitor the distance, check the liquid level, etc. The board is also equipped with a relay and a buzzer that allow the user to provide distance-related acoustic signals or activate/deactivate an external device, such as a pump, brake, etc.
