Q & A

What is the purpose of the spectacles in this project?

The spectacles are designed for people who have difficulty detecting objects in front of them. The system alerts them through a buzzer and a LED when an obstacle is detected.

Which components are required for this project?

The components required are an Arduino Uno board, an ultrasonic sensor, a 5V active buzzer, an LED, female jumper wires, and a power source.

How is the ultrasonic sensor connected to the Arduino Uno board?

The ultrasonic sensor is connected to the Arduino Uno by connecting the VCC pin to the 5V pin of the Arduino, the trigger pin to digital pin 9, the echo pin to digital pin 10, and the ground pin to the ground pin of the Arduino.

What is the role of the active buzzer in this setup?

The active buzzer emits a sound when an obstacle is detected, alerting the user to the presence of an object in front of them.

How is the buzzer connected to the Arduino Uno?

The positive wire of the buzzer is connected to digital pin 11 on the Arduino Uno, while the negative wire is connected to the ground pin.

Where is the LED connected in the circuit?

The positive lead of the LED is connected to digital pin 13 on the Arduino Uno, and the negative lead is connected to the ground pin of the Arduino.

What happens when an object is detected in front of the spectacles?

When an obstacle is detected, the buzzer sounds and the LED lights up, providing a visual and auditory alert.

Can the system be powered by a 9V battery?

Yes, the system can also be powered by a 9V battery connected to the Arduino Uno board.

What is the significance of using jumper wires in the circuit?

Jumper wires are used to make connections between the various components of the circuit, such as the ultrasonic sensor, buzzer, LED, and the Arduino Uno board.

How does the ultrasonic sensor detect obstacles?

The ultrasonic sensor sends out sound waves and measures the time it takes for the waves to bounce back after hitting an object, allowing it to determine the distance to the obstacle.
