A Practical Activity Report Submitted For Engineering Design-Ii (Uta014)

This document summarizes a practical activity report submitted for an Engineering Design course. It describes building an Arduino-based social distancing detector using 4 ultrasonic sensors, an LED, buzzer, and breadboard. When any sensor detects a person within 2 meters, the buzzer and LED activate. Tables list the components used and code uses pulseIn to calculate distances from sensors and trigger the alarm if any reading is under 200cm. Diagrams show the logic and circuit layout. The result is an effective alert system for maintaining safe social distancing.

Assignment-1
1. OBJECTIVE: Arduino based program for a Social Distancing Detector and

execute the program through the simulator.

2. HARDWARE USED: Arduino Uno R3, Breadboard, Piezo Buzzer, 4x

Ultrasonic Distance Sensor, LED, Resistor, Wires.


3. SOFTWARE USED: Tinkercad

4. THEORY: Ultrasonic sensor measures the time difference between the trigger

signal sent to the object and the echo received. This time difference helps us

calculate the distance between the user of and a passer-by. Four sensors are used

so that the blind-spot of the device is reduced. When the device detects a person

within 200m of the user the buzzer is triggered and the LED glows along with it.

Both switch off when it detects there is no-one within 200m of the user.

6. RESULT ANALYSIS:

The circuit is responsive and alerts the user if another person comes within the COVID Social
distance, i.e. 200 cm or 2m thereby reducing the risk of contact from a potential carrier of the
virus.
