This article I want to discuss about electronic circuits. I have discussed quite a lot in previous articles, but after I looked around, it turns out I haven't discussed what an electronic circuit is. So before I go any further, first of all let's look at the computer or television set. We can see in it a line of foreign objects attached to a pair of printed circuit boards. Some of these objects are elliptical, rectangular, rectangular, some are flat and many have unique shapes. These objects are neatly arranged and lined up, quite interesting to look at. These objects are what are called electronic components, such as resistors, capacitors, diodes, transistors, ICs and other components.
From the description above, it can be concluded that an electronic circuit is a series consisting of various electronic components arranged in such a way as to function in accordance with the wishes of the designer.
Basically, in the field of electronics, especially regarding how to assemble an electronic device, all electronic components are not depicted in real physical form, but are expressed in the form of schematic drawings, which are called electronic schemes.
Like the picture above, all components are not depicted in real terms, but only in the form of symbols, codes, symbols, and other signs, each of which has its own meaning.
In making electronic circuits, based on experience, people usually assume that by installing several components according to the circuit schematic drawing, he will feel confident that his experiment will work out well. Technically it might be possible to succeed by chance, but if he fails then he can't do anything.
In learning electronic circuits, besides having to be able to read circuit schematic drawings, you must also understand the types of components that will be used in the electronic circuit that will be made. Apart from that, you must also pay attention to other supporting tools, namely tools such as screwdrivers, pliers, solders, saws, hammers, and others.
It should also be noted that electronic components on the market are generally not always in good condition. The components to be used should be checked first with a measuring instrument called an AVO meter or multi meter. This tool is absolutely necessary for you if you want to assemble an electronic device. Because if you don't test it first with the measuring instrument, the possibility of failure can occur.
Thus a brief description of this electronic circuit. May be useful. Also follow other articles that you may find useful about electronic aids.
