　ALGYANの7周年プレゼント基板のハンダ付けが完成したので、作動テストを始めました。 この基板は沢山の機能が載っているので、プログラムの初心者にとって、一度のプログラムするのは難しいので、少しづつ確認を始めました。 　はじめに定番のエルチカから、TFT LCDディスプレーの表示までを色々やってみました。 Arduino IDEのサンプルを使い、少し書き換えました。 パソコンにＵＳＢ接続をすると、ＥＳＰ３２の赤色ＬＥＤが点灯し、ＬＶＤディスプレーが明るくなります。  ### ＜もくじ＞

### 1. 　エルチカ ボード上の右上にあるグリーンのLEDを点滅させました。 [ALGYAN ７ｔｈ基板でエルチカの動画]@[youtube](https://youtu.be/t2zQO3Rxp4U) ```arduino:エルチカ // ESP32 Div Keit ALGYAN 7th Boad LED Blink int led1 = 26; int tim = 200; // the setup function runs once when you press reset or power the board void setup() { // initialize digital pin LED_BUILTIN as an output. pinMode(led1, OUTPUT); } // the loop function runs over and over again forever void loop() { digitalWrite(led1, HIGH); // turn the LED on (HIGH is the voltage level) delay(tim); // wait for a second digitalWrite(led1, LOW);// turn the LED off by making the voltage LOW delay(tim); } ``` ### 2. 　LEDのアナログエルチカ グリーンのLEDを、段々に暗くしたり、段々に明るくしたりする。 [LEDのアナログ点灯の動画]@[youtube](https://youtu.be/zxBs8JuOV0Y) ```arduino:アナログエルチカ // use first channel of 16 channels (started from zero) #define LEDC_CHANNEL_0 0 // use 13 bit precission for LEDC timer #define LEDC_TIMER_13_BIT 13 // use 5000 Hz as a LEDC base frequency #define LEDC_BASE_FREQ 5000 // fade LED PIN (replace with LED_BUILTIN constant for built-in LED) #define LED_PIN 26 int brightness = 0;

} // wait for 50 milliseconds to see the dimming effect delay(50); } ``` ### 3. 　ＷｉＦｉでＬＥＤをＯＮーＯＦＦ ＷｉＦｉを使って、スマホからＬＥＤのＯＮ－ＯＦＦを制御する。 [ＷｉＦｉでＬＥＤをＯＮーＯＦＦの動画]@[youtube](https://youtu.be/Ka1AFTsT7Wo) ```arduino:ＷｉＦｉでＬＥＤをＯＮーＯＦＦ // use first channel of 16 channels (started from zero) #define LEDC_CHANNEL_0 0 // use 13 bit precission for LEDC timer #define LEDC_TIMER_13_BIT 13 // use 5000 Hz as a LEDC base frequency #define LEDC_BASE_FREQ 5000 // fade LED PIN (replace with LED_BUILTIN constant for built-in LED) #define LED_PIN 26 int brightness = 0;
