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 ...

環境Arduino Uno Arduino IDE 2.0.3 3端子レギュレータ（LM7912L） 3端子レギュレータ定格3Vのウォーターポンプに12Vの電源を使いたい。3端子レギュレータで電圧を下げられると見たのでやってみる。 回路図 結果 出力電圧が小さすぎてモーターが回らなかった。

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 ...

Use a state machine and the function millis() instead of delay() Use tank treads instead of wheels. Introduce electronics and programming to my kids. There are a lot of tutorials on the internet that ...
