Lesson17: Tracing Human Movement

lession17.inoのWiFi書き換えてアップロード

色がチカチカ光り意味がわからないが、安定する位置で動作確認してみる。

White (透明) LEDはWebでは白くてstatusが見えない・・・

まず、色々試す。

Yellow LEDはWebもstatusが見えないので、反転。

距離は、

コードに２行加えてモニターする。

Serial.println(distance);
Serial.println(status_str);

↓こんな感じ。

OSOYOO Smart Home IoT Learning Kit with MEGA2560 でつくるSmart Home Lesson16。

Lesson16: RFID Switching Door

RFID.zipがライブラリとして必要。

https://github.com/osoyoo/Osoyoo-development-kits/blob/master/Osoyoo%20Yun%20IoT%20Smarthome%20Kit/Libraries/RFID.zip

からダウンロードしていつもの手順でインポート。

lesson16をアップロードしたがエラーが出たので、まずチュートリアルを実行。

https://osoyoo.com/2019/10/14/osoyoo-mega-iot-shield-rfid-tutorial/

テストでRFID Moduleの確認。

https://osoyoo.com/driver/smarthome/osoyoo-mega-iot-rfid.ino

いつものようにアップロード。

動かない・・・

LEDが赤い？？

と思えば、RFIDカードをかざして番号が出るんですね。

かざせはOK。

16:32:26.824 -> Find the card!
16:32:26.824 -> The card's number is : 121,218,61,194,192
16:32:26.899 -> Not match!

で、Sketch書き換えてOK。

16:38:24.143 -> Find the card!
16:38:24.143 -> The card's number is : 121,218,61,194,192
16:38:24.178 -> This card match our record!

次は、smarthome-lesson16.ino

RFIDの番号を書き換え、WiFiを変更。今度は問題なくアップロード完了。

webも表示。

RFIDを近づけると

16:48:16.162 -> Find the card!
16:48:16.162 -> match

はでるが、何も動かない。

WebでClose Doorを押すとRed LEDが点灯し、

WebでOpen Doorを押すとGleen LEDが点灯。（Red LEDは消灯）

Close状態からRFIDをかざすとモータが動き、LEDもRedが光るようになった。

Turn Off Buzzerを押すと、モーターがぎこちなく動き続ける状態になり挙動がおかしい。

Buzzerがいつなるのかと思えば、別のRFID IDを近づけると鳴った。

ひとまずOK。

14:51:25.604 -> New client
14:51:26.920 -> [WiFiEsp] Disconnecting 1
14:51:26.954 -> Client disconnected

青のジャンパーケーブルと緑のジャンパーケーブルを接触させるとブザーがなるので、リレーがうまく作動していないように見える。

ひとまずここまでで後回し。

Smart Home IoT Kit Lesson12: Light Sensor

IoT

OSOYOO Smart Home IoT Learning Kit with MEGA2560 でつくるSmart Home Lesson12

Lesson12: Light Sensor

これも動作しないというか、光を検出していない？

何しても no light

別途考えよう・・・・。

ということで振り返りながら。ソースをみる。

gasStatusを使っていることから、流用していると思うのだが特に問題でないためそのまま使用することにする。

gasStatus=digitalRead(light_sensor);

gasStatusを0、1で切り替えるようになっているが、それではわからないのでアナログで吐くようにする。

int gasStatus=0;//の下に

int val = 0; //追加

void loop()
{ // の後ろに２行追加
val = analogRead(light_sensor); // 追加
Serial.println(val); //追加し、アナログで表示

を加えて、ジャンパーを接続しても接続を外しても、

22:50:36.714 -> No light
22:50:36.747 -> 1023
22:50:36.747 -> No light
22:50:36.747 -> 1023

と永遠に1023なので、ググると

"1023" indicates that the resistor or the ground wire are not properly connected.

つまり、つながっとらん？？

それならばと

A0からA1にPnP PINを変更し、sketchも

//#define light_sensor A0
#define light_sensor A1

と変更。

モジュールのディップスイッチもD→Aに変更し、デプロイ。

やっと検知。。。

22:57:16.088 -> No light
22:57:16.088 -> 944
22:57:16.088 -> No light
22:57:16.088 -> 944
22:57:16.124 -> No light

22:57:16.338 -> 399
22:57:16.338 -> sound detected
22:57:16.373 -> 390

って、使い回しだからSoundになってるよ。せめてLightにしとこう。

Lesson11: Sound Sensor

Micro Phoneモジュールに、Buzzerの音を近づけても検知せず。壊れているのかな？？？

何しても no noise
