Hardware plays a crucial role in the Raspberry Pi environment as it determines the capabilities and functionality of the system. This article aims to provide an informative and instructional overview of hardware components commonly used with the Raspberry Pi, highlighting any adaptations necessary for this specific environment.

Examples:

1. Power Supply: The Raspberry Pi requires a stable power supply to function properly. It is recommended to use a power adapter with a micro USB connector that can provide a voltage of 5V and a current of at least 2.5A. To check the power supply status on the Raspberry Pi, use the following command:

   vcgencmd get_throttled

2. Storage: The Raspberry Pi relies on external storage for storing the operating system and user data. One common option is to use a microSD card as the primary storage medium. To format and mount a microSD card on the Raspberry Pi, follow these steps:

   sudo fdisk /dev/mmcblk0
   n
   p
   1
   <default>
   <default>
   w
   sudo mkfs.ext4 /dev/mmcblk0p1
   sudo mount /dev/mmcblk0p1 /mnt

3. GPIO (General Purpose Input/Output): The GPIO pins on the Raspberry Pi allow for interaction with external hardware devices. To control a GPIO pin programmatically, use the RPi.GPIO library in Python. Here's an example of turning on an LED connected to GPIO pin 17:

   import RPi.GPIO as GPIO
   import time
   
   GPIO.setmode(GPIO.BCM)
   GPIO.setup(17, GPIO.OUT)
   
   GPIO.output(17, GPIO.HIGH)
   time.sleep(1)
   GPIO.output(17, GPIO.LOW)
   
   GPIO.cleanup()
