beginners guide - getting started with arduino.

what is arduino?

The arduino board is small microcontroller board,which is small circuit that contains a whole computer on a small chip that is microcontroller. Arduino is one of the platform which provide the microcontroller to put sketch on it.

Arduino is composed of two parts:-

1.Arduino board (hardware)

2.Arduino integrated development environment(software)

Arduino board:-

Arduino is piece of hardware we work on it.

The above picture shows the different types of arduino boards which has different memory capacity and used depending upon the required application. The arduino has row of pins as we can see in picture which is used as input and output pins. These pins are used to connect sensors and actuators. A sensors senses something in physical environment and converts it to a signal a computer can understand which again converted into human understandable form, while actuators converts signal from computer into an act in physical world.

Arduino integrated development environment:-

The IDE is a software we can run on computer. The IDE is is used create a sketch and then uploaded to the arduino board. The sketch instructs the board what to do.

The above picture has written with little sketch which turns on a LED on for one second and then off for one second. working on hardware meant building circuits using hundred of transistor, resistors, capacitors, inductors and so on. Thus making changes required to cut the wire and very difficult disconnect once solder is made between the components, While software is easier to modify than hardware with a few keypress we can change the logic of the device.
