This project was inspired by Paul McWhorter. The project includes an HC-SR04 Ultrasonic sensor which measures the target distance and displays it onto an LCD.I made this so it is easier to measure the distance of objects.

EXPANDED TECHNICAL DETAILS

Handheld Spatial Measurement interface

A technical blueprint for building a compact, battery-powered distance meter that provides high-resolution data on a portable LCD.

  • HC-SR04 ultrasonic Pulse-Cycle Timing: The Arduino manages the trigger and echo handshake with microsecond resolution. The firmware calculates the distance and provides a real-time update rate of 10Hz.
  • Precision Floating-Point Display: Renders the distance in Centimeters, Inches, and Feet simultaneously on a 16x2 I2C display. Includes a "Hold" button to freeze the current measurement for easy reading.

Efficiency

  • Sub-Microamp Battery Management: Includes a "Auto-OFF" feature; if no distance change is detected for 5 minutes, the Arduino enters a deep sleep mode to preserve the 9V battery.
