So, these are the main benefit of using the technology of Raspberry Pi.
Now that the definition and benefit of Raspberry Pi is clear let’s focus on,
How to Setup and Start Raspberry Pi?
The board of Raspberry Pi includes an SD card. This SD card acts as the primary storage system of the Raspberry Pi board. Onto this card, a Linux Operating system, which is bookable in nature, is loaded. It is essential to mention here that along with Linux; Raspberry Pi supports Qtonpi, Mac and ARM operating systems as well. First, one will have to select one specific Operating system and then write it on the SD card with the help of a Disk Manager Application. Apart from this, one can make use of other forms of storage mechanism like an external USB hard drive or a USB drive. The SD card that is supported by Raspberry Pi is up to 64 GB. So, these fundamentals that one must remember before using a Raspberry Pi technology.
Before beginning to use Raspberry Pi, one will have to connect a keyboard, display, mouse, just like it is done for a PC. The Raspberry Pi supports 3 different kinds of Outputs such as composite video, DSI video, and HDMI Video. However, in the case of DSI video, there is a requirement of specific hardware. Upon buying a Raspberry Pi board, one might find the board to be sold without or with an SD card, which is a crucial specification in the board of Raspberry Pi. This is because of the fact that the SD card helps in keeping the operating system, programs and documents.
One of the most significant benefits of using Raspberry Pi is that it can work as a usual computer, comes in small size and is a cost-effective server that can correctly handle greater web traffic.
Some applications of Raspberry Pi
Raspberry Pi boards are found to use in several kinds of applications that includes Arcade machine, Media streamer, Tablet computer, Carputer, Internet radio, home automation, controlling robots, and so on.
1. Motor speed control based on Raspberry Pi
The motor speed control that is based on Raspberry Pi is generally developed with the intention of controlling the speed of a DC motor. For this application, the hardware and software requirements are – a DC motor, a television set, PC monitor, motor driver IC, LED, resistors, capacitor, diode, voltage regulator, PHP program, transformer, and last but not least, the Raspberry Pi model.
In this application, to control the DC motor, the Raspberry Pi board is utilized by connecting a keyboard to it for running the motor at different speeds.
2. Use Raspberry Pi for auto intensity control of street lights
Another fascinating application of Raspberry Pi is auto intensity controlling of street lights. The hardware and software required for performing this project are – transformer, capacitors, diodes, resistors, LEDs, Raspberry Pi board, a PC monitor or TV and MOSFET, crystal, PHP program and white LEDs. To control the intensity, the Raspberry Pi board is utilized for developing pluses width modulation signals for driving a MOSFET that turns on the LEDs to get the desired function. After this, one will observe that the intensity of the LEDs will vary from evening to next day morning, especially during the peak hours.
So, these are two of the best applications of Raspberry Pi.
So far, it has been well-established that Raspberry Pi is an exciting technology and concept. Therefore, let’s find out more regarding,
