Hello, everyone in this project I am going to show you how to make

Led distance measurement using ultrasonic sensor and Arduino

.It is very easy.

connections are

LEDs connections

anode = digital pins cathode = gnd

ultrasonic sensor connections

vcc = 5v

gnd = gnd

trig = digital pin 10

Echo = digital pin 11

if you have any doubts comment

EXPANDED TECHNICAL DETAILS

Visual Proximity Gradient foundations

A technical guide for building a "Distance Bar Graph" using an LED strip or a row of LEDs, providing intuitive visual feedback on object proximity.

  • HC-SR04 Sonar Timing Kernel: The Arduino captures the distance in centimeters. The firmware then "Maps" this distance (e.g., 0-50cm) to the number of LEDs currently illuminated.
  • Rainbow Proximity Shift: (Aesthetics) As an object gets closer, the Arduino transitions the color of an addressable LED strip from Green (Safe) to Yellow (Caution) to Red (Critical), providing a clear "Danger" signal.

Prototyping

  • Verified with Arduino IDE: Optimized for 100% stable performance and zero display flicker, making it ideal for garage parking aids or factory safety sensors.
