Where RASPBERRY PI 3 is Used?
RASPBERRY PI platform is most used after ADRUINO. Although overall applications of PI are less it is most preferred when developing advanced applications. Also the RASPBERRY PI is an open source platform where one can get a lot of related information so you can customize the system depending on the need.
Here are few examples where RASPBERRY PI 3 is chosen over other microcontrollers and development boards:
1. Where the system processing is huge. Most ARDUINO boards all have clock speed of less than 100MHz, so they can perform functions limited to their capabilities. They cannot process high end programs for applications like Weather Station, Cloud server, gaming console etc. With 1.2GHz clock speed and 1 GB RAM RASPBERRY PI can perform all those advanced functions.
2. Where wireless connectivity is needed. RASPBERRY PI 3 has wireless LAN and Bluetooth facility by which you can setup WIFI HOTSPOT for internet connectivity. For Internet of Things this feature is best suited.
3. RASPBERRY PI had dedicated port for connecting touch LCD display which is a feature that completely omits the need of monitor.
4. RASPBERRY PI also has dedicated camera port so one can connect camera without any hassle to the PI board.
5. RASPBERRY PI also has PWM outputs for application use.
There are many other features like HD steaming which further promote the use of RASPBERRY PI.
How to Use RASPBERRY PI 3
As mentioned earlier PI is simply a COMPUTER ON A SINGLE BOARD so it cannot be used like ARDUINO development boards. For the PI to start working we need to first install OPERATING SYSTEM. This feature is similar to our PC. The PI has dedicated OS for it; any other OS will not work.
We will discuss the programming of PI in step by step below.
- Take the 16GB micro SD card and dedicate it specifically for PI OS.
- Choose and Download OS software. [https://www.raspberrypi.org/downloads/] (‘NOOBS’ recommended for beginners )
- Format the SD card and install OS on to the SD memory card using convenient methods.
- Take the SD card after OS installation and insert it in PI board.
- Connect monitor, keyboard and mouse
- Power the board with micro USB connector
- Once the power is tuned ON the PI will run on the OS installed in the memory card and will start from boot.
- Once all drivers are checked the PI will ask for authorization, this is set by default and can be changed.
- After authorization you will reach desktop where all application program development starts.
On the PI you can download application programs required for your use and can directly install as you do for your PC. After that you can work on developing required program and get the PI run the developed programs.
