What is Arduino ?
Arduino is an open-source electronics platform device that is easy-to-use hardware and software.
They consist of a physical programmable circuit board also referred to as a microcontroller and software IDE (Integrated Development Environment) that use to write and upload computer code to the device.
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.
Arduino has been used in many projects like home automation, smart parking, GPS trackers, lighting products, musical instruments, robots, smart toys, drones, etc.
