2. What is
RASPBERRY PI?
OMega TechEd
• The Raspberry Pi in IoT is a low-cost, small computer
used as a gateway or edge device for connecting and
managing smart devices.
• It collects data from sensors, processes it locally, and
sends it to the cloud if needed. With built-in Wi-Fi and
Bluetooth, it easily integrates with IoT networks.
• It’s programmable, supports various IoT protocols, and
is ideal for applications like smart homes,
environmental monitoring, and industrial automation.
• Its affordability and flexibility make it popular for IoT
development and deployments.

4. Developing Raspberry Pi involves these steps:
1. Hardware Setup: Connect Raspberry Pi with power, microSD card (with OS
installed), monitor, keyboard, and optional hardware (e.g., sensors, cameras).
2. Install Operating System: Use Raspberry Pi OS or another compatible OS on
the microSD card and boot it up.
3. Programming: Write code in languages like Python (popular for GPIO
control) or C++.
4. GPIO & External Devices: Use GPIO pins to connect and control sensors,
motors, and other devices.
Example: Control an LED connected to the Raspberry Pi:

5. Example
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT)
# Blink the LED
for i in range(5):
GPIO.output(18, GPIO.HIGH)
time.sleep(1)
GPIO.output(18, GPIO.LOW)
time.sleep(1)
GPIO.cleanup()
This line imports the RPi.GPIO library and assigns it the alias
GPIO.
This line imports Python's built-in time module, which provides time-
related functions, such as sleep.
This line sets the pin numbering scheme to BCM mode.
This line configures GPIO pin 18 as an output pin.
This line creates a for loop that will repeat 5 times.
This line sets GPIO pin 18 to HIGH
The program pauses for 1 second to keep the LED on.
This line sets GPIO pin 18 to LOW, cutting off the power to
the pin.
This line resets the GPIO settings.

5. Remote Access: Enable SSH or VNC for remote development, or run network-
based applications (e.g., IoT, web servers).
Enable SSH via Raspberry Pi OS Desktop Interface
• Open the Start Menu (Raspberry icon in the top left).
• Go to Preferences and select Raspberry Pi Configuration.
• In the Interfaces tab, find SSH and select Enable.
• Click OK to apply changes.
6. Build & Test: Create applications like home automation, IoT projects, or
robotics. Debug and test with IDEs like Thonny or VS Code.

To connect via SSH:
Find the Raspberry Pi’s IP address
hostname –I
Use an SSH client from another
machine to connect:
ssh pi@<IP_ADDRESS>

7. Difference between Arduino and Raspberry Pi
Raspberry Pi
• A single-board computer. It runs a full
operating system (usually Linux-based)
and can perform complex tasks like web
browsing, media playback, or running
servers.
• Runs a complete operating system, usually
Raspberry Pi OS, supporting multitasking,
networking, and software like Python, web
servers, etc.
• Supports high-level programming
languages such as Python, C/C++, Java,
and can use software development
environments like VS Code.
Arduino
• A microcontroller board. It executes
simple, low-level tasks like reading
sensors or controlling motors directly.
It does not run an OS and focuses on
real-time control.
• No OS. Programs (sketches) are written
in C/C++ and run directly on the
hardware, controlling pins and
connected devices.
• Primarily programmed using Arduino
IDE in C/C++ with simple, event-
driven code (loop and setup functions).

8. Difference between Arduino and Raspberry Pi
Raspberry Pi
• Includes a processor (CPU), RAM, HDMI
output, USB ports, and networking (Wi-Fi,
Ethernet), making it more powerful.
• Requires more power, usually via a 5V,
2.5–3A power supply.
• Best for complex projects needing
computing power—like IoT gateways,
media centers, web servers, robotics with
vision, etc.
• Has built-in Wi-Fi, Bluetooth, USB ports,
HDMI, and GPIO pins for interacting with
hardware.
Arduino
• Simple microcontroller (like ATmega328),
limited RAM and storage, and lacks the
ability to run complex software.
• Low power consumption can run on
batteries (e.g., 9V) for long periods.
• Best for simple electronics projects—
such as controlling LEDs, motors, sensors,
and real-time systems where quick pin
control is necessary.
• Focuses on GPIO pins, with additional
components (shields) needed for network
connectivity (Wi-Fi, Ethernet, etc.).

9. Conclusion
 Raspberry Pi is a minicomputer for complex
projects and multitasking.
 Arduino is a microcontroller for real-time
control and simpler electronics tasks.
Choose the Raspberry Pi for software-based
projects and the Arduino for hardware-centric, real-
time applications.
