right now from now on the world of Arduino. A little late challenge, but I bought an ESP32

Is it difficult at this age? I started with Arduino, I did a little bit a few years ago, but I found it difficult to give up. I'm going to study Scratch from now on,
First of all, I bought this to update his DAC for Nanopi-neo2 and Raspberrypi Zero music servers. Currently a 24bit 198Khz DAC made about 10 years ago
I'm using , but I'm making a DAC to replace it. There is a wall of Arduino, so I think it is impossible for the time being, but I would like to try.

It's ESP32 for 1260 Yen I am going to make a USB DAC with it

First, install the latest version of Arduino2 or higher. Download and install the appropriate application for your PC from the Microtechnica website. In my case it will be 64bit Linux.
Download the application, decompress it and pass it through the path to start it. Below is the initial screen, it's not like the Arduino 1.8 screen, but I think it's basically the same. Easier to see.
It seems that the old version is easier to use. Both the old model and the new model are still inexperienced, so it is necessary to compile and practice more and more from now on.
I learned today that the Raspberrypi pico was an Arduino. With permission from her wife, I ordered one. I'm having a hard time living, but I'm going to use this and Raspberrypi pico.
I have over 20 years of experience working with Linux, but I can't program. From now on, I'm going to whip my old body and study. I think it will take at least a year. I say that's normal. It's about learning python.

this is Raspberrypi pico but actually works as Arduino

Arduino 2.0.0

How do I write it next? Even if I'm aware of it and I can't write a scratch yet, I don't know how to write a program to this ESP32, so I was very troubled. Test LED Blink with Arduino
I've done it several times, and it was so difficult that I forgot about it. I was curious about it, but I couldn't compete with it at my level, so I forgot about Arduino. It was several years ago. It was a board that was not a regular version for about 1500 yen.
I experimented with an oscilloscope, but I forgot about it because it was not practical. I thought it was useful, but the level was high and I could not spend time.
Now, this time, I'm going to try again with Arduino, focusing on using my brain because I've lost Raspberrypi B+. The ESP32 is an Arduino, and the Raspberrypi Pico is also an Arduino. because it is a controller
It cannot be used as a PC. It is a promising CPU as a PC interface. It's a little result that I can't write data in the middle of the day, and I can do it by chance. Below is the image.
I have a sample program that handshakes USB and UART.

This is the screen where he wrote an example scratch and executed a program called AnalogRead Serial drawn by his predecessor

To be continue ^^ ^l^ this part of page is using google donky traduction from my bad Japanese, so very sorry

In this section, we are experimenting with Nanopi-Neo2,
but the same thing can be used with Raspberrypi's one board PC as long as you are using a Debian OS.
