ArduinoUnoで定刻になったら処理をするプログラムを作りたかった。 そこでシステム時刻を取得したかったけど方法がわからんので、millis()関数を使って疑似的に作った。 スケッチブックディレクトリに上記のソースファイルを配置する。 あとは使用例のよう ...

The Arduino Development Platform, at the beginning in 2005, was conceived to be a simple programmable device to be used specifically for art design work. The goal was to create an interface to support ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

Welcome! This is my solution for using the millis function to create a clock. Keep in mind that the oscillator of the arduino is not very preciced. I recommend to use a real-time-clock if you got the ...

One of the most commonly asked Arduino-related questions is how to write one’s programs in such a way that they can accommodate an overflow/wraparound condition in the millis() function. One of the ...
