What is Arduino?

Arduino is an open-source electronics platform device that is easy-to-use hardware and software.

It is a physical programmable circuit board or also referred to as a microcontroller and to write and upload computer code to the device there is a software IDE (Integrated Development Environment).

The Arduino IDE uses the C++ Programming language to program the device.


The Arduino environment is very simple to use for beginners who have no knowledge of software or electronics.

Those boards are inexpensive so you can buy them easily and also anyone can build their own because they are open-source electronics platform hardware.

With these boards, we can build objects that can respond to and/or control light, touch, and movement.

It has been used in many projects like home automation, smart parking, GPS trackers, lighting products, musical instruments, robots, smart toys, drones, etc.

For Beginners, we recommend Arduino UNO because it is easy to use.

Components Description


Mainly it has a USB port for uploading programs from the computer to the board. It has a microcontroller which controls the input/output signal. It has power pins that we use to provide power to the sensors. In this board, there are digital and analog pins. There is also a reset button inboard to reset the program. It has LEDs to showing the board status.
