Arduinoスケッチを描いていると、WiFiのSSIDやパスワードといった秘匿値をデバイスに渡してやらないといけないことが多々ありますよね。 インターネットにあるスケッチをみていると、たいてい、 const char* password = "PASSWORD"; のようにソースコードにハード ...

This Arduino project controls a magical box (or book) using a servo motor, a hidden button, and an internal light. When the hidden button is pressed, the box slowly opens and the LED lights up — ...

というわけでJAMMAからVGAを分配する中間コネクタを作成してたら副産物として垂直同期信号を出力できるようになったのでついでに垂直同期信号によって完全にシンクロしたコマコンを作ろうかなと 現時点ではアイデアを整理している状態なので各種AIを ...

This project demonstrates an Arduino-based LCD button counter using the Arduino UNO R4 WiFi and an I²C LCD display. The sketch counts button presses, debounces the input, toggles an LED, and displays ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

While newer Arduinos and Arduino compatibles (including the Hackaday.io Trinket Pro. Superliminal Advertising!) either have a chip capable of USB or rely on a V-USB implementation, the old fogies of ...

Usually, I use the Serial Monitor of the Arduino IDE to communicate with the Arduino hardware. But now, I want to build an application on my computer that allows me to click some buttons to control ...

A few months back at the Black Hat Security conference Cody Brocious demonstrated how you can easiy open an Onity hotel room lock, the standard system used in many hotel chains, with an Arduino but it ...
