3. Aim and Objectives
Aim
 To construct a programmable Arduino car robot to detect and measure
object
Objective
 To connect various car robot components to Arduino
 Write a programming code for Ultrasonic sensor, servo motor and motor
controller
 Examine each programmed component

4. Introduction
 This project is meant to demonstrate how a car robot is programmed to
move around, also has the features to measure and detect object from
distance

5. List of components
 Arduino uno Servo motor SG90

6. • Double weels • DC motor drive SG90

7. • Male anf female connecting wire • L298 motor controller

8. • Breadboard Ultrasonic sensor (HC-SR04)

9. Hardware Assemble steps
