Make An Ultrasonic Detection And Ranging Device at Home

i want to make a Alarming radar but it failed i will try again but today I am going to guide you to Make A Ultrasonic Detection and ranging device at Home using an Ultrasonic Sensor(Transceiver) i know there are many project and and i also accept that codes are not mine i just found them on Github and then made the circuit (i will add the credit after finding the original auther and coder) , In the next post i will post my own project Alarming buzzer.lets back to the today post This radar System is made by.Arduino Board and a servo motor.You can call it Small and short range radar system because it works/detects obstacle in between 2cm to 450cm distance.With the help of Coding and Processing Software we can see the data on a graph on the computer screen.”
