Arduino IDE Program Interface:
This is how the Arduino IDE programming environment running on your computer looks like. We are starting to get acquainted with its interface. Now we will not touch the code, but only tell you about the purpose of the function keys in the program menu.
The following shows the most important commands used in new projects, such as check, upload, new, open, save, serial monitor port, sketch name, code drop and message area. Sketches of new projects are checked if loaded correctly. After that, the scheme should work. If the sketch and the diagram are incorrect, then the malfunction is eliminated. After all, the scheme should work.

4.1. Electrical circuit
An electrical circuit is an unbroken path along which an electric current can flow from the starting point to the end point, for example, from plus to minus. Electrical circuits can contain resistors, diodes, transistors, motors, and more. The scheme can contain a huge number of such elements.

Circuits are generally divided into three categories: analog circuits, digital circuits, and mixed-signal circuits. In this guide, you will explore all three sets of circuits.
