「小型のM5 Atomを何かにドッキングさせることで、子供でも手軽に楽しめるものが作れないか?」という思いから作成しました。その際、口下手な子供の趣味を友達にアピールするには?を考えた際、LEDが適しており、NeoFlash HatはRGB色で表示でき、コンパクトかつ低価格で作れるため、これで作品を制作しました。
For my son who is not good at communicate with friends, NeoFlash Hat was the good tool because it is one of the smallest LED with RGB and cheep.

- Toys: Children who cannot yet communicate well can appeal to other children.
- Meet up: a message accessory so that the other party can easily find you.
- Events: As a walking advertisement, keep playing an appealing message
This content is the simulated "the announcement of Tohoku-Shinkansen (bullet train)" which my son like.
①ATOM Echoに、②LED/電源ユニット(LED:NeoFlash Hat+バッテリー:ATOM TailBAT+クリップ)を接続すると、コンテンツがLEDと音声(内臓スピーカー)から再現されます。
This LED clip is consit of "1. ATOM Echo" & "2. LED & Battery unit (LED:NeoFlash Hat + Battery: ATOM TailBAT + Tie Clip)". The contents will start when you combine "ATOM Echo" and "LED & Battery unit" via USB/Grove connector. NeoFlash Hat is for M5Stick C but it can be use for ATOM Echo if we connect with the 3 PINS: GND, 5V and GPIO26.
Arduino IDEを用いて、各種ライブラリ、サンプルを参考に作成しています
The program has written with Arduino IDE. I would like to thanks a lot to many programers who shared own experiences about M5Stack and ESP32. LED and Sounds (Wave music & Speech in Japanese) have managed by the Dual Core functions of ESP32. About LED management, 1. Adafruit GFX library is useful for NeoFlash Hat as well. It can be scroll in English and dot animations. 2. For Japanese, Misaki fonts & Tamakichi lib which is 8x8 size is suitable for NeoFlash Hat. About Sound management, Japanese is able to speech with Aquestalk on the I2S speaker of ATOM Echo. Also it can sound WAVE music.
