Electronic projects may be built using the open-source Arduino platform. A software program called the IDE (Integrated Development Environment) that runs on your computer is used to create and upload computer code to the actual programmable circuit board that makes up the Arduino. This software is commonly referred to as a microcontroller.
For those who are just getting into electronics, the Arduino platform has grown fairly popular. The Arduino, unlike the majority of earlier programmable circuit boards, can be updated with new code using just a USB cable rather than a separate piece of hardware (called a programmer). Additionally, the Arduino IDE employs a condensed form of C++, making programming simpler to learn.
Features Of
Arduino
Price-wise, Arduino boards are affordable when compared to other microcontroller architectures.
Programming environment that is easy to understand and use – The Arduino Software (IDE) is versatile enough to be used by both novice and experienced users. It's built on the Processing programming environment, which is helpful for teachers because it means that students learning to program in that environment will be familiar with how the Arduino IDE operates.
Open source and extensible software - Arduino software is made available as an open-source tool that skilled programmers may modify. People who wish to learn more about the technical aspects of the language can go from Arduino to the AVR C programming language, on which it is based, and the language can be expanded through C++ libraries. The same is true for adding AVR-C code straight into Arduino programs.
The Arduino boards' blueprints are made available under a Creative Commons license, allowing skilled circuit designers to create their own version of the module, extending and upgrading it. This makes the hardware open-source and expandable. To learn how the module functions and to save money, even very unskilled users can create the breadboard version of it.
Arduino UNO
The best board to start with when learning about electronics and programming is the Arduino UNO. The UNO board is the most durable one you can start with if this is your first time tinkering with the system. The UNO is the Arduino family's most popular and well-documented board.
An ATmega328P-based microcontroller board is the Arduino UNO. It contains 6 analog inputs, a 16 MHz ceramic resonator, a USB port, a power connector, an ICSP header, and a reset button. It also has 14 digital input/output pins, six of which may be used as PWM outputs.
It comes with everything required to support the microcontroller; to get started, just use a USB cable to connect it to a computer, or an AC-to-DC converter or battery to power it. Without too much concern, you can experiment with your UNO; in the worst case, you can replace the chip for a few bucks and start over.

1. Energy USB
The Arduino board may be powered by your computer's USB cord. Simply attaching the USB cable to the USB connection is all that is required.
2. (Barrel Jack) Power
By connecting it to the Barrel Jack, Arduino boards may be powered directly from the AC mains power source.
3. Voltage Regulator
The function of the voltage regulator is to control
the voltage given to the Arduino board and stabilize the DC voltages used by
the processor and other elements.
4. Crystal Oscillator
Arduino can manage time-related concerns thanks to the crystal oscillator. How is time calculated by Arduino? The crystal oscillator, that's the solution. The number 16.000H9H is written on the crystal of the Arduino board. The frequency is specified as 16 MHz or 16,000,000 Hertz.
5. Arduino Reset
You may start your program over by doing a reset on your Arduino board. The UNO board may be reset in two different ways. the reset button on the board, first. Second, you may attach a reset button externally to the Arduino pin designated RESET.
6. Micro Controller
There is a separate microcontroller on each Arduino board (11). You might consider it to be your board's brain. Each Arduino board has a slightly different main IC (integrated circuit). The ATMEL Company typically manufactures microcontrollers. Before loading up a new program from the Arduino IDE, you must be aware of what IC your board has. The top of the IC has access to this information. You can consult the datasheet for further information on the IC's design and functions.
