Introduction

Smartphones are becoming increasingly important in the world of technology, especially in the context of IoT. They have become an indispensable tool for various applications.

Microcomputers, specifically smartphones, have emerged as the primary medium for interaction with Raspberry Pi.

Setup Process

Using your Android or iOS mobile along with a Raspberry Pi, you can easily set up your smartphone as a keyboard for your mini PC.

Step-by-Step Guide

Change the password and username distribution to enhance security against potential cyber threats.
Open the terminal on the microcomputer and execute the following commands:

sudo apt-get update && upgrade
sudo apt-get install realvnc-vnc-server realvnc-vnc-viewer
These commands will facilitate the installation process.

Execute the raspi-config command and navigate to the VNC option. Activate the VNC option to establish a connection.
Register for free at RealVNC for Raspberry Pi.
Download the client for Raspberry Pi from their website and install the VNC app on your mobile device.
Use your access credentials in VNC Viewer to remotely control the desktop from your smartphone or through a web application.

This setup allows you to control the microcomputer not only from the terminal but also from other devices such as desktop computers or laptops.

Best Applications for Controlling Raspberry Pi
