No more frustration! Re-introduction to Electronics

I' ve tried electronics in the past, but I hit a wall and fell behind along the way.

It's true that when you're just starting to try electronics, you often get frustrated for a variety of reasons!

This time, I would like to talk about the theme of "re-introduction" to electronics work for those who are no longer frustrated.

In addition, this time using a technique called web scraping, We used a technique called web scraping to retrieve all 10,000+ posts related to "electronics" on Yahoo Chiebukuro, We analyzed and summarized them.

We have categorized the reasons for your setbacks into types (1), (2), and (3), and considered countermeasures for each of them.

Please read this article to the end as it will help you resolve the causes of your frustration.

Let's take a look at the causes and countermeasures for each type of setback.

Type 1: Purpose but lack of knowledge

The first type is for those who "have a purpose but lack the knowledge The following is a countermeasure for those who "have a purpose, but have been frustrated due to lack of knowledge.

I have a purpose, but I don't have the knowledge.

Picking up some of the questions in Wisdom Bukuro, it seems that many people have a clear idea of what they want to make, such as an automatic curtain opening/closing device or a music device, but have been frustrated by a lack of knowledge.

Those who fall into this type (1) have a clear idea of what they want to make, so to some extent they can visualize the necessary parts.
However, they are often stumped because they do not know how to move them.

I know the parts, but I can't move them.

In such cases, we recommend that you read these books first to gain a minimum of electronics knowledge.

Electronics book

The first is "100 Basics of Electronics".

This book is a little bit old. Although the book is a bit old, it is a very good summary of the knowledge that is always necessary in electronic construction, such as the goods that should be prepared for electronic construction, the functions of frequently used electronic components, and how to read schematics.

100 Electronics Basics

I have read many books for beginners, butIhonestly don' t think I have ever read one that is so well put together!

One bottleneck is that the microcontroller board used is called a PIC microcontroller, which is a bit of a hurdle for beginners, so it is better to just look at and read about chapter 7 as a reference.

100 Electronics Basics

And once you have learned the basics, you can get used to using the microcontroller board by actually working with it in the "Practical Arduino" section here.

Practical Arduino

The main reason I recommend this one is that the gadgets you make with the samples are by far the most fun compared to other books! The most important reason for recommending this book is that the gadgets you make with the samples are far more enjoyable than other books.

Practical Arduino

All of these things have never been seen before, and moreover, while you are having fun making them, you can learn how to program them and how to use sensors in one step.

If you want to gain knowledge, please read these two books first to learn the function and use of each component!

Measures with objectives but no knowledge

Type 2: Knowledgeable but without purpose

continuedType (2) is the case where "I have some knowledge, but I lost motivation and became frustrated due to a lack of purpose.

I have the knowledge, but not the purpose.

Again, I picked up some of these from the Wisdom Bags!

In the submissions of those who said they were electrical students or liked electronics, many of them seemed to have some knowledge of the subject, but had lost their purpose because they did not have anything in particular they wanted to make.

I have the knowledge, but not the purpose.

This state of affairs inevitably leads to a lack of energy and frustration.

These people are encouraged to visit events and sites that inspire them!

Visit events and sites

First of all, as far as events go, I would recommend the Maker Faire.

In fact, it is a favorite place for me to visit when I was not feeling up to it.

Maker Faire

Maker Faire
is an annual event where individuals who make things gather to exhibit their works, and is now held in various locations throughout Japan.

The three recommendations are as follows

Recommendations for Maker Faire
  1. High level of work
  2. Works of various genres are exhibited and unexpected discoveries are made.
  3. Feel free to talk to the person who made it.

Feel free to talk to the creator.

When I ask questions, everyone readily shares their know-how with me, so I can get hints on how to make things.

We can also hear about the hardships that go on behind the scenes to make a work look good, which can give us courage.

It gives me courage.

I always have my phone in hand and try to jot down any ideas as soon as they fall into my lap!

One site we recommend is called "GUGEN," which is Japan's largest electronics contest.

six objective fields of the senses (shape and colour, sound, scent, flavour, physical feeling, and mental presentation)

is held once a year in real life, so of course we recommend that as well, but the site also includes all past works, so you can view as many as 1,000 works from the comfort of your own home.



If you don't know what to make, please take a look at these two events and websites first!

Type 3: No purpose or knowledge

The last type (3) is "those who have no purpose and no knowledge The last type (3) is "those who have no purpose and no knowledge and have failed.

No purpose, no knowledge.
This type is the most difficult to counteract, but it is actually the most common in number.

We saw quite a few postings that fit this type in the Wisdom Bags.

A common point that can be seen is that they have no knowledge but want to start somewhat as a hobby, or that they are interested in trying it.

No purpose, no knowledge.

Knowledge and Purpose Without both, you tend to be in a state where you don't know exactly where to start, which inevitably lowers your motivation.

I don't know where to start.

In most cases, these people do not have an image of what they can do with electronics in the first place.

What can you do with electronics?

As a countermeasure, we recommend the approach of first experiencing electronic construction through hands -on experience.

Hands-on experience

In that sense, we strongly recommend this introductory kit for electronics construction from the manufacturer ELEGOO.


The points we recommend areThere are two.
The first point is that the basic flow of electronic construction, " input, calculation, and output," can be experienced.

Basic flow of electronic construction

As shown in the image below, the system contains a good balance of sensors corresponding to the input part, a microcontroller board corresponding to the calculation, and motors corresponding to the output.

What's in ELEGOO

The second point is that the tutorial that comes with it is very easy to understand.

Each component has its own chapter, for example, the servo motor chapter contains the following



To be honest, I had never seen a tutorial that had all the "schematic, breadboard diagram, and actual product" pictures, and I was even impressed at first.

Easy-to-understand tutorials

As for my impression of the actual process, I still felt a sense of security when so much information was available, and I felt that care was taken to ensure that no one would make a mistake.

I highly recommend this kit to anyone who has never done electronics before!

What people who lack the knowledge of types (1) and (3) should certainly keep in mind is that they should find someone they can ask immediately when they don't understand something.

Find someone you can ask right away.

It is not limited to electronics, but when you try something you have never done before, I am sure you will have questions one after another. I think.

The quickest way to do this is to look for information on the Internet, but the Internet does not actually contain much information on "what is already common knowledge in the industry.

The following, for example, are common knowledge in the electrical world, so no one explains such things on the Internet any longer.

Common Sense in the Electrical World
  • Always connect resistors to LEDs together.
  • Resistor and LED positions can be swapped.
Always connect resistors to LEDs together.Resistor and LED positions can be swapped.

It's just that, For those who are new to circuits, even that part is difficult to understand, and questions like, "Why do you have to put resistors on every single circuit? and so on, and they stop.

Lack of knowledge

It is reassuring to have someone close by to ask questions at such times, and it is easy to maintain motivation!

If there is no one aroundIf so, we hope you will make use of our website , "Electronic Crafts Starting Today".

We have tried to create articles and videos on this site that will help you as much as possible so that you do not get tripped up from the first entrance, and we are sure that we can help you.
We look forward to hearing from you directly!

This is why I have explained the measures to avoid setbacks for each type.

What to do now by type

Finally, here is a summary of what you should do now after reading this article, according to type.

Causes of setbacks by type

If this article has motivated you in any way, please keep up the intensity and carry out these activities.

First, if you are type 1), buy these two books.

Type 1 Measures

I recommend the e-book version because you can start reading it right away.

For Type 2), first visit the GUGEN website and look at the entries for any year.

Type 2 Countermeasures

Each piece is filled with ideas, and I recommend seeing them all, regardless of whether they have won an award or not.

If you are type (3), buy an ELEGOO introductory kit now.

Type ③ Measures


In this issue, we have positioned this as a "re" introduction to electronics work for those who have been frustrated in the past, and have introduced measures to avoid frustration for each type.

I hope this article will make you feel a little bit inspired to start electronics work again.

In future articles, I will discuss more specifics for those who have stepped into the world of electronic construction again, so please see that as well.
