だいぶ前にLEDを使用したリストウォッチの作成を試みたのですが筐体をどうやって作ろうかとずーっと作業止まったままです。。。
現在作製中のペアウォッチ! 筐体どないしよ。。。 #neopixel #Arduino #Trinket pic.twitter.com/EcpHmjSkmC

備忘録としまして、中身のことについて記載していきます（上の写真の右側の方の）。
目次
構成
部品
- NeoPixel Ring – 16連フルカラーシリアルLED
秒針を青、長針を緑、短針を赤で表現しています。
- Adafruit I2C通信の8×8ミニLEDマトリックス基板（緑色）
時刻や日付などを表示
Arduino向けライブラリは以下の2点使用
https://github.com/adafruit/Adafruit_LED_Backpack
https://github.com/adafruit/Adafruit-GFX-Library
- リアルタイムクロックモジュール(RTC) DS3231
正確に時間を計測してくれる。温度センサも内蔵！しかし安い！！！！
Arduino向けライブラリは以下
https://github.com/jarzebski/Arduino-DS3231
- Adafruit Pro Trinket – 3V 12MHz
制御用マイコン
- Adafruit Pro Trinket バッテリーモジュール
Pro TrinketとLiPoバッテリー間に接続し、USB接続時は充電してくれる
- リチウムイオンポリマー電池400mAh
ちょっと分厚いかな。。。。。。？
動作
タクトスイッチを押すと8x8LEDマトリックスディスプレイに各種モードで表示します。
- 時刻表示
- 日付表示
- 温度表示
- グラフィック表示
時刻が切り替わる際に干支の絵がピコピコ表示します。

一回り小さいレディース用も作製途中なので いずれブログ書きます。
どうやって筐体作ろうかな。。。。。(´・ω・｀)？
