HANDS-ON PROJECT


                 PROJECT NAME: Reverse Parking System

                 Software Used: TinkerCad

                 Objective:

                 Learn to design a smart sensing system that detects objects and provides feedback using an
                 ultrasonic sensor and piezo buzzer. This project introduces sensor integration, circuit design, and
                 programming basics.


                 Step-by-Step Instructions:

                 Step  1   Basics of the Ultrasonic Sensor

                             Components and Pinout:

                              o  VCC: Power supply pin.

                              o  GND: Ground pin.

                              o  TRIG: Sends the ultrasonic pulse.
                              o  ECHO: Receives the reflected pulse.

                             Working Principle:

                              o  The sensor sends sound pulses via the TRIG pin.

                              o   It calculates the distance by measuring the time taken for the pulse to reflect and
                                 return to the ECHO pin.

                             Arduino Connection:

                              o  VCC – Connect to 5V on Arduino.

                              o  GND – Connect to Ground on Arduino.
                              o  TRIG – Connect to digital pin 9 for example.

                              o  ECHO – Connect to digital pin 10 for example.

                 Step  2   Piezo Buzzer for Feedback

                           Piezo  Buzzer is  a  simple  sound  device  that  generates  beeps  using  piezoelectric
                           principles.

                             Connection to Arduino:

                              o  Connect the positive terminal to a digital pin (e.g., pin 11)

                              o  Connect the negative terminal to ground.
