What is Raspberry Pi & How It Works?
Raspberry Pi is a tiny computer that allows you to harness the power of modern computing technology to seamlessly deal with mundane computing tasks and everything you would expect a desktop to do. To put it simply, it is basically a computer you can get in a compact size and at an affordable price. Raspberry Pi becomes interesting when you explore its versatility and it is the perfect choice to do a lot of innovative and cool projects.
It is common for our brain to raise the next most logical question: “how does it work?” It works just like any computer that needs to be connected with a power supply and external peripheral devices. Installed with Linux, an open operating system, all the Raspberry Pi models come with WiFi and Bluetooth except Raspberry Pi Zero. These small, versatile, inexpensive, and super portable computers are perfect for any DIY project. Moreover, Raspberry Pi computers have the best aftersale support and a wide range of accessories available, making them efficient and strongly recommended.
How to Program Raspberry Pi?
The first thing you need to get started while programming a Raspberry Pi is installing the operating system. Raspberry Pi allows you to be more independent when it comes to operating systems. Even though Raspbian OS (a Debian-based operating system engineered specifically for Raspberry Pi users) is commonly used, you can also use a wide range of third-party operating systems. These are downloadable from the official website for free.
Once you have downloaded the latest version of Raspbian OS, or Windows 10 for IoT core, Ubuntu, or any available operating system, it is as simple as setting up any other operating system. If you chose the Raspbian OS, you would see the simple account setup dialog box. After creating an account and checking all the peripherals connected to the system, you would see that it is similar to any other operating system, which lets you do all your tasks with a simple user interface.
Things to Do with Raspberry Pi
From replacing your restricted desktop OS to creating new innovative projects, Raspberry Pi opens a whole new world of possibilities and an inexpensive way to play with your ingenuity. While there are many things you can do with this microcomputer, we are listing a few you might find interesting to know about.
Raspberry Pi has been growing in popularity and now has real-world applications in different industries. It can be used for monitoring industrial equipment, programming smart cars, and more. It has great usage in the manufacturing and automotive industries. Hotels are using it to streamline their business processes, and municipalities are using it in waste management (by checking the level of the trash bins).
With Raspberry, you can monitor multiple parameters in the field of agriculture. It can be used in irrigation systems, soil moisture monitoring, temperature sensors, and more. These are critical parts of farming, and streamlining the process with the smart technology of Raspberry Pi is very useful, especially in rural areas. Monitoring can be done from anywhere, thus saving time and costs.
Retro Gaming Machines
For most young teenagers who buy this microcomputer, setting up a retro gaming machine would be the main reason to buy it. With Raspberry, you can effortlessly revive almost any 16-bit game console and have it up and running in less than an hour.
Building Innovative Tools
Apart from being a gaming console, Raspberry Pi allows you to do several other amazing things. Creating your own tool is one such thing you can experiment with Raspberry Pi. You can create several cheap and creative monitoring tools by integrating IoT and Raspberry Pi.
Project Hub and Learning Tools
Raspberry Pi can be effortlessly used as a perfect device to create IoT projects and cool college projects. As it was specifically designed for constructive purposes, Raspberry Pi is the perfect choice for various creative and innovative projects and for learning programming languages.
How to Use Raspberry Pi in IoT Projects?
By integrating IoT with Raspberry Pi, you can give life to your creativity and let your imagination run in the most simple and time-saving way. Did you know that the population of connected IoT devices is over 30 billion as of 2020, surpassing the human population? Even though it is impossible to replace heavy IT infrastructure with Raspberry Pi, setting up a low-cost server for handling websites, testing IP connectivity, and building dashboards for data visualization with Raspberry Pi are some useful projects.
IoT Project Examples Using Raspberry Pi
Creating DIYs using IoT is becoming more popular and enables many young students and professionals to create various simple tools. By leveraging IoT and Raspberry Pi, you can transform a tedious task into something exciting and easy even with limited technical knowledge. Below are some of the most innovative and simple projects you can try by combining IoT and Raspberry Pi.
IoT-Based Water Level Monitor
If you have a garden at home or probably agricultural land, you know the importance of the water level you need to prevent the plants or crops from drying out. Well, you can install a monitoring system to check the water levels! All you need to have is a relay module, a pipe and a hose, an Arduino, a Bluetooth HC, a soil moisture sensor, wires, and some technical knowledge.
An IoT-Based Smart Home System
Building smart home systems DIYs is one of the most popularly experimented projects using IoT and Raspberry Pi. Even the simplest home task can become tiring for some people due to their busy schedules. People who want to experiment with automating some of the most mundane household tasks can develop a multipurpose home automation tool using Bluetooth and Raspberry Pi. All you need to do is just connect the tool to the appliances and operate them remotely.
