Let's start from here
If we want to make or test any device, we must possess some simple knowledge and it is not required to delve deeper into knowledge. What is important to us is knowing only the basic principles, and many, many people think that making a metal detector or any electronic device requires many skills and knowledge in electronics, and this is wrong, and correct That you can start by learning the basic things only to get started, and from here the metal detector industry requires only some knowledge that you can master only with one day of learning.
Today, with the blessing of God, we begin to learn by watching short videos for an hour. If you focus on these videos, you will learn making, God willing, in one day only. A human being is only required to insist on learning and knowledge.
Here in this topic we will learn the basic things only such as resistors and their colors and distinguish between them as we will learn the transistors that we can use and how we know their legs and how we know if they are valid or damaged, we will also learn about the normal capacitor and its values and the variable capacitor and how to extract it and finally we will look at the ic555 and its usefulness and how we use it in Our metal detector circuits.
I told you at the beginning, if you focus only for an hour in the videos published on this topic, you will learn, God willing, and I am talking, so what is required is only focus
Now let's watch the videos together and know that if a person does not try to learn, he will not learn:
