Story

Do you have important family or friends who live far away?

You sometimes want to call, email, or get in touch with them.

But in your busy daily life, you tend to forget about them. Has that ever happened to you?

We've created a gadget to help you remember those important people.

1, Introduction

I wanted to make a gadget to display in my room.

Many of the ornaments I have in my room were purchased while traveling.

Looking at them reminds me of my travels.

I thought it would be interesting to have a gadget that would remind me of family and friends who are far away, so I made this piece.

2, How does it work

To remind you of your family and friends, the weather where they live is expressed through light, sound and wind.

Weather information is obtained using the OpenWeather(https://openweathermap.org) API.

By entering location information (latitude and longitude) into M5Stack, it will access the OpenWeather website via WiFi to obtain weather information for that location.

If the received weather information indicates severe weather such as heavy rain, thunder, or a storm, it will be expressed with LED (light), sound, and fan wind.

Rain: LED and Rain sound

Thunder: LED and Thunder sound

Storm: LED and Fan wind

Weather information is updated every 30 minutes.

Also, when entering location information, you can also enter the birthday of someone you want to remember.

When that day arrives, the M5Stack screen will notify you ("Congratulations")

If the change in weather reminds you of family and friends, why not get in touch with them after a long time?

3, Hardware

The equipment configuration is as follows:

4, How to use

4.1, Preparation

Set up WiFi to connect M5Stack to the internet.
Create an OpenWeather account.
MP3 file to play the sound.

4.2, Assembly

The housing is made using a 3D printer.
Make a board that connects the LED, power wiring, and signal wiring

The wind is generated using an M5 fan module.I removed the fan and installed it inside the case so that the wind would flow outside.

4.3, How to use

Obtain the latitude and longitude information of the location you want to check the weather. You can find the latitude and longitude on Google Maps.

Enter latitude and longitude using the M5Stack buttons (+, -, Enter).

Enter the anniversary date.
Once you've finished entering the information, you're done. If there are any changes in the weather, this gadget will notify you with light and sound. The weather is updated every 30 minutes.
If you notice a light or sound, why not contact a family member or friend? It will be a happy occasion for both of you to have a conversation after a long time.

●ストーリー

遠くに住んでいる、大切な家族や友人はいますか？

たまに電話をしたり、メールを出したり、連絡をしたくなるような。

しかし忙しい日常でその友人の事をわすれてしまう。そんなことはありませんか？

そのような大切な人の事を思い出すためにこのガジェットを作りました。

1, イントロダクション

部屋に飾るガジェットを作りたいと思いました。

部屋に飾っているオーナメントは、旅行先で購入したものが多いです。

それを見ると、旅の事を思い出します。

そのように遠くにいる家族や友人を思い出すきっかけとなるガジェットがあれば面白いのではないかと思い、この作品を作りました。

2, 動作の説明

家族や友人を思い出すきっかけとして、その人たちが住んでいる場所の天気を光や音、風で表現します。

天気情報の取得にはOpenWeather(https://openweathermap.org) のAPIを使用します。

場所の情報（緯度、経度）をM5Stackに入力すると、WiFiでOpenWeatherのサイトにアクセスして、その場所の天気情報を入手します。

入手した天候情報が、大雨、雷、嵐等激しい天候の場合、それをLEDと音声, ファンの風で表現します。

雨：LEDと雨音

雷：LEDと雷音

風：LEDとファンの風

天気情報は30分ごとに更新します。

また、場所の情報を入力する時に、思い出したい相手の誕生日等も入力しておきます。その日が来たらM5Stackの画面で知らせてくれます("Congratulations")

天候の変化で家族や友人の事を思い出したら、久しぶりに連絡を取ってみるのはどうでしょうか？

3, ハードウエア

機器構成は上の画像を参照ください。

4, 使い方

4.1, 事前準備

・M5Stackをインターネットに繋ぐためWiFiの設定が必要になります。

・OpenWeatherのアカウントを作成する必要があります

・音を鳴らすためのMP3ファイルが必要になります。

4.2, 組立

・筐体は３Dプリンタで作成します。

・LEDと電源線、M5StackのI/Oピン配線を載せた基板を作ります。

・風はM5のファンモジュールを使って発生させます。風が外部に流れるようにファンを外して筐体側に取り付けました。

4.3, 使い方

1, 天気を調べたい場所の緯度、経度情報を入手します。緯度、経度はGoogleMapで調べる事が出来ます

2, 緯度と経度を入力します。入力はM5Stackの三つのボタン（+, -, Enter）を使います。

3, 記念日を入力します（記念日になると画面にCongraturationと表示されます）

4, 入力を終えたら終了です。あとは設定した場所で天気の変動があった場合に光や音であなたにお知らせします。天候の情報は３０分ごとに更新されます。

5, 光や音に気づいたら、家族や友人に連絡を取ってみてはいかがでしょうか？久しぶりの会話はお互いにとって嬉しい出来事になるはずです♪
