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 ...

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 ...

arduinoでmillisを使用し、タクトスイッチを押すとLEDを点滅させる。 タクトスイッチは二個、タクトスイッチ一個につきLED二個使用する。 スイッチ1はLEDが交互に光り、スイッチ2はLEDがそれぞれ異なる周期の点滅を繰り返す。 「0」は消灯状態から始まり ...

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 ...

This library implements 64 bit time counters optional with offset. It also provides 32 bit versions with optional offset. These functions were inspired by code from docdoc to count millis() rollOvers.

It’s possible to write one’s programs in such a way that they can accommodate an overflow/wraparound condition in the millis() function, but how does this actually work? It’s possible to write one’s ...

Looking for something to do in his downtime, [Mista Sparkle] decided that building a simple stroboscope was in order. He already had a set of six LEDs connected to his Arduino from a previous project, ...
