The first thing you will need is a computer.
In electronic construction, programming is done on what is called a CPU or microcontroller, and in many cases this is done using a personal computer. However, there is no need to have particularly high specifications, and even a 10-year-old PC will do just fine. Also, recently, programming software is compatible with various operating systems, so if you are just starting out in electronic construction, I think either Windows or Mac is fine. However, be aware that you may not be able to install an older OS.
If you are unable to prepare a computer, you can do simple electronics work with Sony's MESH device or obniz, a microcontroller board specialized for the IoT, from your smartphone.
The next thing you need is components.
As explained in this video, electronic devices are made up of the flow of input, calculation, and output, so you will need components for each.
Components for calculation are called CPUs or microcontrollers, and are generally used in what is called a microcontroller board, which is a single package with useful functions for electronic construction. If you want to buy a microcontroller board for your first electronic construction project, you should definitely buy an Arduino microcontroller board. There are endless types of components for inputs and outputs, and they vary greatly depending on what you want to do. If you don't have a clear idea of what you want to build, buy a beginner's kit from a manufacturer like ELEGOO or OSOYOO sold on Amazon. The microcontroller board included in these kits is the manufacturer's own, but the microcontroller and interface are the same as Arduino's, so you don't need to worry about it too much.
The next thing you need is tools.
The first thing you need to have in terms of tools is a breadboard, nippers, tweezers, wire strippers, and radio pliers.
These are used to cut cables to the proper length, connect cables together, and grab small parts. Since electronic work involves a lot of detailed work, these specialized tools will make your work outstandingly easier and stress-free.
You should also have a complete soldering iron set. The soldering iron set here consists of a soldering iron, solder, an iron stand, and a desoldering wire. Since the suitable temperature varies depending on what is to be soldered, we recommend a soldering iron, preferably a sound-toned type. Solder should be environmentally friendly lead-free solder, and buy an iron holder with as solid a base as possible. We do not recommend cheap ones, as they fall over quickly and are quite useless.
In addition, you will want to have a case for storing the components along with the electronic components. Many parts are very small, and it is often difficult to tell what kind of parts they are at a glance, so buy a case as soon as possible and sort them before it is too late. There are an infinite number of types, so you can choose according to your preference. 100-yen stores are fine, or you can go to a large home improvement center where you can choose from dozens of different types. By the way, I mainly use Muji storage cases, and I put parts in transparent sachets and manage them by category.
The last thing I would like to introduce is laboratory equipment.
This is the most expensive part if you get particular about it, but for the time being, I think it is okay if you only have a tester.
A single tester can measure voltage, current, resistance, etc., and is useful in many areas of electronic construction. You can choose from a variety of testers for as little as 3,000 yen.
I will show you how to use the tester in another video.
Finally, as an added bonus, I would like to introduce a few things that are not essential but are useful to have.
First is an oscilloscope. An oscilloscope is a measuring instrument that allows you to monitor voltage in real time. You can also view voltages with a tester, but a tester only displays averaged values over time, so you cannot see voltage changes that are short in time. For example, if you try a 1 kHz pulse from 0 to 3.3 V, the tester will average out to 1.65 V. With an oscilloscope, you can see the waveform. They cost several tens of thousands of yen at the cheapest, but they are quite useful when verifying the operation.
The next useful thing is a stabilized power supply. When you are doing electronic construction, there are times when you want to do a little experiment such as running a motor or seeing how the brightness of an LED changes depending on the voltage.
