What Is Arduino?

Arduino is an open-source electronics prototyping platform that is widely used by makers, designers, and hobbyists because it is convenient and easy to use. It can read input signals from various sensors and generate outputs by controlling lights, motors, and other devices. For beginners, it is a powerful tool for learning open-source hardware. You do not need to study registers, digital logic, or other specialized knowledge separately. It is like 1 + 1 = 2: you do not need to understand where 1 comes from, why it is 1, or why the equals sign is written that way. You only need to follow simple rules and know that 1 + 1 = 2.

What Can Arduino Do?

Have you ever wanted to build a remote-control car that you can control yourself?

Have you ever wanted to build a robot that can draw on the ground or travel through snow?

Have you ever wanted to build Iron Man's arm cannon?

Have you ever wanted a Professor X steampunk wheelchair with voice and delivery functions?

Arduino can help you make these ideas real, and it can get you started with intelligent control. Remote-control lights, obstacle-avoidance cars, automatic plant watering, thermohygrometers, game consoles, controllers, remote-control cars, remote-control boats, and many other projects are possible as long as they can be programmed, connected to circuits, and do not require heavy computation. In short, if a microcontroller can do it, Arduino can usually do it too. It can be used to create all kinds of innovative projects, from simple blinking LEDs to complex robotic systems.
