サーボモーターSG90が半分の角度しか回らないので調査


https://www.rocher.kyoto.jp/arbr/?p=1763 に対処方あり

dc-dc stepdown convertorで3.3vをとりだすとesp01がつかえる

servoは上記をとおさず5vをとりだし、制御は3vロジックでいけた

最終コードは

#include <Servo.h> // servo library  
 Servo s1;  
 void setup()  
 {   
  s1.attach(0,500,2400);  // servo attach gpio0 pin of esp01 
 }  
 void loop()   
 {  
   s1.write(0);  
   delay(1000);  
   s1.write(90);  
   delay(1000);  
   s1.write(180);  
   delay(1000);  
 }

https://makers-with-myson.blog.ss-blog.jp/2017-01-14 を参考に

ＰＷＭのFREQ/DUTYをセットして成功した　DUTYは１０００くらいまで設定しないと

モータがうごかんかった　PINMODE設定不要だったこと(行儀わるし、書くべし）

https://www.ei.tohoku.ac.jp/xkozima/lab/espTutorial0.html　にFREQ目安あり

PWM 周波数が高いほど、使用可能なデューティ分解能は低くなり、その逆も同様です。

https://micropython-docs-ja.readthedocs.io/ja/v1.19.1ja/library/machine.PWM.html　より

const in ledPin = 2;

void setup(){

　　pinMode(ledPin,OUTPUT);

     analogWriteFreq(1000);

     analogWriteRange(1000);

}

void loop(){

  digitalWrite(4,LOW); // drv8833用、stby3.3vわすれずに

  for(int dutyCycle=0;dutyCycle<1000;dutyCycle++){

    analogWrite(ledPin,dutyCycle);

   delay(10);

  }

 for(int dutyCycle=0;dutyCycle<1000;dutyCycle++){

    analogWrite(ledPin,dutyCycle);

   delay(10);

  }

}
