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
22:57:16.124 -> 944
22:57:16.124 -> No light
22:57:16.124 -> 944
22:57:16.124 -> No light
22:57:16.162 -> 510
22:57:16.162 -> No light
22:57:16.162 -> 498
22:57:16.162 -> No light
22:57:16.196 -> 487
22:57:16.196 -> No light
22:57:16.196 -> 476
22:57:16.196 -> No light
22:57:16.230 -> 468
22:57:16.230 -> sound detected
22:57:16.230 -> 457
22:57:16.230 -> sound detected
22:57:16.268 -> 446
22:57:16.268 -> sound detected
22:57:16.268 -> 431
22:57:16.268 -> sound detected
22:57:16.304 -> 419
22:57:16.304 -> sound detected
22:57:16.338 -> 409
22:57:16.338 -> sound detected
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。
