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.
