Ultrasonic Range Finder with RP2040-Zero & LVGL GUI
This project is an ultrasonic range finder built using the RP2040 Zero board and a 3.2-inch TFT display. It utilizes the RCWL-1655 sensor, which operates similarly to the popular HC-SR04, to measure distances ranging from 20cm to 300cm. The device features a Relay and a Buzzer, each with its distance threshold. All settings, including the thresholds and buzzer status, can be adjusted using a simple graphical user interface (GUI).
