GENERAL VİEW GENERAL VİEW The main objective of our project is to design an instrument that measures height of a person or an object standing some meters away. The main objective of our project is to design an instrument that measures height of a person or an object standing some meters away. We will use ardunio uno microcontroller and an ultrasonic sensor for this project. We will use ardunio uno microcontroller and an ultrasonic sensor for this project.

ABOUT OUR PROJECT ABOUT OUR PROJECT We will use an ultrasonic sensor to send and receive a high frequency sound We will use an ultrasonic sensor to send and receive a high frequency sound We will use Arduino uno to control the servo motor, LCD and ultrasonic sensor We will use Arduino uno to control the servo motor, LCD and ultrasonic sensor And we will use a servo motor to move our ultrasonic sensor by fixed amount of degrees. LCD display for displaying the height of an object. And we will use a servo motor to move our ultrasonic sensor by fixed amount of degrees. LCD display for displaying the height of an object.

ARDUNIO UNO ARDUNIO UNO In our project we aim to use arduino uno microprocessor that will control the servo motor, LCD Display and Ultrasonic sensor. To control these parts we write a code in arduino software and then we upload it to microcontroller.

ULTRASONİC SENSOR ULTRASONİC SENSOR We will use Ultrasonic sensor HC- SR04.Ultrasonic sensors (they both send and receive sound) work on a principle similar to radar or sonar. Ultrasonic sensors generate high frequency sound waves and evaluate the echo which is received back by the sensor. Sensors calculate the time interval between sending the signal and receiving the echo to determine the distance to an object.

SERVO MOTOR LCD Display Arduino will measure the height of an object after that it displays this data on LCD. We will use servo motor in our project to move the ultrasonic sensor by fixed amount of degrees. We will use servo motor in our project to move the ultrasonic sensor by fixed amount of degrees.

Plan Of The Project We aim the ultrasonic sensor to the base of an object using a LASER, arduino saves the distance to the base, after that a push button is pressed and system starts to scan an object by rotating the sensor by 10 degrees (can be modified). When sensor detects objects top part it stops scanning. Distance to the top is saved by arduino. Using the amount of steps made by servo motor, angle between bottom, sensor and top is determined. Using cosine theorem arduino calculates the heihgt of scanned object.

What we have done up to now? We did research about the project We did research about the project Decided on which sensor could be used. Decided on which sensor could be used. Almost finished design of the project both circuitry and structure. Almost finished design of the project both circuitry and structure. Searched for necessary components. Searched for necessary components. Bought almost all necessary components. Bought almost all necessary components. Did some trials. Did some trials.

What will we do? Until this time,we were focusing on construction and how we can do our project and ordering main components. From now on we will Deal with mistakes we made in our code for ardunio microcontroller. Deal with mistakes we made in our code for ardunio microcontroller. Test and calibrate our instrument for good accuracy. Test and calibrate our instrument for good accuracy.
