Raspberry Pi and Arduino - Go to The Next Level - Activity 09 - Solution

This tutorial guides you through setting up an Arduino and Raspberry Pi system to take photos every two seconds and send them via a Telegram bot. It covers configuring the Raspberry Pi camera, integrating a Telegram bot for photo requests, and using serial communication to trigger photo sending with a button press. The tutorial emphasizes modular code and offers improvements for handling file access during photo updates.

What is the primary task introduced in the beginning of the tutorial?

• To take a photo every two seconds

• To control a motor

• To send a message every two seconds

• To read temperature data

Which library is used to handle the camera on the Raspberry Pi?

• OpenCV

• PiCamera

• ImageMagick

• CameraKit

What is the purpose of setting the camera's resolution to a small size?

• To save storage space

• To reduce processing time

• To enhance color accuracy

• To improve image quality

What is the role of the Telegram bot in this project?

• To send and receive photos

• To update software

• To manage user accounts

• To control the Raspberry Pi remotely

What improvement is suggested for handling photo files?

• Reducing the photo size

• Using unique filenames for each photo

• Increasing the photo delay

• Using a higher resolution

What action triggers the sending of a photo in the improved process?

• A voice command

• A button press

• A timer event

• A motion sensor

What is the purpose of the serial communication setup?

• To connect to the internet

• To send photos upon button press

• To update the Raspberry Pi firmware

• To control a servo motor

Which component is used to detect button presses?

• A proximity sensor

• A light sensor

• A temperature sensor

• A push button

What is the significance of the 'chat ID' in the Telegram bot setup?

• It identifies the user sending the command

• It specifies the photo resolution

• It determines the photo delay

• It sets the camera rotation

What is the final goal of integrating Raspberry Pi functionalities in this project?

• To design a basic temperature monitoring system

• To build a simple LED control system

• To develop a complex program combining multiple functionalities

• To create a standalone camera system
