A step-by-step guide on how to connect your Raspberry Pi to the internet and access it remotely using tools like SSH, VNC, or web interfaces.

Method 1: Connecting via SSH (Secure Shell)

SSH is a powerful tool that allows you to access and control your Raspberry Pi remotely over the internet. It provides secure shell access to the terminal of your Raspberry Pi, enabling you to execute commands and manage files on it.

First, make sure your Raspberry Pi is connected to a network with internet access. You can use an Ethernet cable or connect to Wi-Fi if your Raspberry Pi has a wireless adapter.
Open the terminal (either through VNC, SSH, or directly on the device) and update the system:
```
sudo apt-get update && sudo apt-get upgrade
```
Install openssh-server if it’s not already installed:
```
sudo apt-get install openssh-server
```
Ensure that SSH is enabled by running the following command:
```
sudo systemctl enable ssh
```
Get the IP address of your Raspberry Pi by running:
```
hostname -I
```
On your local machine, open a terminal and type:
```
ssh pi@<IP address>
```
Replace <IP address> with the IP of your Raspberry Pi. When prompted, enter the default password raspberry. You can now access your Raspberry Pi remotely through SSH.

Method 2: Connecting via VNC (Virtual Network Computing)

VNC allows you to view and control the graphical interface of your Raspberry Pi remotely over the internet. This is useful for running graphical applications or when you need a visual interface.

First, make sure your Raspberry Pi is connected to a network with internet access.
Install VNC server by running:
```
sudo apt-get install tightvncserver
```
Configure the VNC server by running:
```
vncserver :1
```
You’ll be prompted to set a password for accessing the VNC server. Enter and confirm your preferred password.
To connect to the VNC server from another device, install a VNC viewer such as TightVNC or RealVNC. Enter the IP address of your Raspberry Pi and the display number you chose (in this case, :1) in the VNC viewer’s connection settings.
When prompted, enter the password you set earlier to access your Raspberry Pi remotely through VNC.

Method 3: Connecting via NoMachine NX

NoMachine NX is a powerful remote desktop tool that provides high-speed and secure access to your Raspberry Pi over the internet. It’s especially useful for controlling graphical applications or accessing a full desktop environment remotely.

First, make sure your Raspberry Pi is connected to a network with internet access.
Install NoMachine NX server on your Raspberry Pi by running:
```
sudo apt-get install nomachine-server
```
Create an account for the NoMachine server and set a password:
```
sudo nxserver --register
```
Start the NoMachine server:
```
sudo nxserver --start
```
Install the NoMachine client on your local machine from the NoMachine website.
Open the NoMachine client and enter the IP address of your Raspberry Pi, your username, and password when prompted. You can now access your Raspberry Pi remotely through NoMachine NX.

Note: Be sure to configure your router settings to forward ports for each method if you’re connecting from outside your local network. Also, make sure to keep your Raspberry Pi updated and secure by regularly applying updates and changing default passwords.
