I've correctly wired up an Arduino Nano 33 BLE to a 4-channel AC dimmer from RobotDyn and noticed that the output signal produced by calling digitalWrite(D6, HIGH) is oscillating which results in the ...

このプログラムでは、ArduinoでDCモーターの速度と回転方向を制御します。スイッチや半固定抵抗器を使って、モーターをON ...

It seems like the second argument of digitalWrite is expecting a constant from PinStatus. However this isn't always ideal, and we get an ugly warning like shown below ...

①Arduinoの5VピンとGNDピンをブレッドボードに接続 ② 赤のLED2個と緑のLEDを1個をブレッドボードに差し込む ③ LEDそれぞれの短い方の足に220Ωの抵抗器を接続 ④ 抵抗器の反対側をGNDに接続 ⑤ 緑のLEDの長い方の足をArduinoの3番ピンに接続 ⑥ 赤のLEDの長い方の足 ...

Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...
