  2. JavaScriptならこれだけのコードで エアコンのリモコンなどを操作できる @akaa07_pg <script src=“https://unpkg.com/[email protected]/obniz.js”></script> <script> var obniz = new

    obniz(“obniz_ID_HERE”); obniz.onconnect = async function () { // 赤外線コマンド受信 var sensor = obniz.wired('IRSensor', {vcc:0, gnd:1, output: 2}); sensor.start(function (arr) { console.log(JSON.stringify(arr)); }); // 赤外線コマンド送信 var infraredLed = obniz.wired(‘InfraredLED’, {anode: 1, cathode: 3}); infraredLed.send([1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, … ]); </script>
  3. obniz.jsの中身を 見てみると、 「logicAnalyzer」 というものを 使っているっぽい class IRSensor { // 省略

    start(callback) { // 省略 this.obniz.logicAnalyzer.start({ io: this.params.output, interval: this.dataSymbolLength, duration: this.duration, triggerValue: this.dataInverted ? false : true, triggerValueSamples: this.triggerSampleCount, }); // 省略 } } @akaa07_pg
  4. // PHP // obnizへの指示はJSON配列で送る $obniz_commands = [ [ 'logic_analyzer' =>

    [ 'io' => [2], 'interval' => 0.07, // サンプリング周期 ‘duration’ => 500, // サンプリング期間 ‘trigger’ => [ // 取得開始のトリガー 'value' => true, 'samples' => 16 ] ] ], ]; @akaa07_pg // JS class IRSensor { // 省略 start(callback) { // 省略 this.obniz.logicAnalyzer.start({ io: this.params.output, interval: this.dataSymbolLength, duration: this.duration, triggerValue: this.dataInverted ? false : true, triggerValueSamples: this.triggerSampleCount, }); // 省略 } } コア機能とパラメータを調べて実装
