material needed:

-Arduino UNO

-Ultrasonic Sensor


-2-LED s



-LCD(liquid crystal display)



Step 1: Next Complete the Circuit Use the Schematic As Shown

Step 2: After Complete the Circuit Upload the Code

if your tag is not the same as mine change the tag id in the code .

Step 3: See the Video for More Information
