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 ...

In this tutorial we are going to interface a seven segment display to ARDUINO UNO. The display counts from 0-9 and resets itself to zero. Before going further, let us first discuss about seven segment ...

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 ...

Despite a wealth of tutorials for setting up and writing code for the ESP8266 WiFi module, there has not been much of anything on programming this cheap wireless module with the Arduino IDE. Finally, ...
