Raspberry Pi: the smallest PC
#What is The Raspberry Pi?
The Raspberry Pi is a low cost, credit-card sized computer that plugs into a Computer monitor or TV and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing and to learn how to program in languages like Scratch and Python.
#How does the Raspberry Pi Work?
An SD card inserted into the slot on the board acts as the hard drive for the Raspberry Pi. It is powered by USB and the video output can be hooked up to a traditional RCA TV set, a more modern monitor, or even a TV using the HDMI port.
#Raspberry Pi board Structure:
Depending on the model, the Raspberry Pi has either 40 or 26 dedicated interface pins. In all cases these include a UART, an I2C bus, a SPI bus with two chip selects, I2S audio, 3V3, 5V and ground .The maximum number of GPIO can theoretically be indefinitely expanded by making use of the I2C or SPI bus.
There is also a dedicated CSI-2 camera port for the Raspberry Pi Camera Module ad a DSI display port for the Raspberry Pi LCD Touch Screen Display. So, it means we can use a Raspberry Pi as our personal computer.
#Uses of Raspberry Pi:
- Using Internet
- Learning Program
- Controlling ROBOT
- Playing Games Natively
- Retro Gaming Machine
- Building a Mine Craft Game Server
- Building a Stop Motion Camera
- Broadcasting a Pirate FM Radio Station
- Building a smart mirror etc…

#Raspberry Pi Price:
The price of a Raspberry Pi depends on its model. In our country (BD) the price is between 4000tk-6000tk. The global price is given on internet.
#Why we should learn Raspberry Pi using:
Raspberry Pi is a long lasting micro computer. A Raspberry Pi works at least 5 years without any problem. With a Raspberry Pi one can learn programming and build many useful devices by his own. It is so enjoyable that one can use his leisure time properly. It has no disadvantage. So, everyone should learn and know about it.
