もっと良い方法があったので別の記事を書いた RTC、リアルタイムクロックモジュール（DS1302を搭載したモジュール）で時刻合わせをする方法 ...

Real-time environmental monitoring is increasingly important in agriculture, industrial automation, smart homes, and healthcare. The real-time data monitoring ...

These days, you could be forgiven for thinking driving an LCD from a microcontroller is easy. Cheap displays have proliferated, ready to go on breakout boards with controllers already baked in. Load ...

The most popular RTC for the Arduino is the DS1307. However, it does have some drawbacks, the most notable of which is that its operating voltage is 5v, which means it cannot be used with 3.3v ...

[Kaushlesh Chandel] prototyped a few projects on his Arduino that use an HD44780 Character LCD. Wanting to keep these projects in one piece, but not sacrifice his Arduino board, so he etched his own ...

As promised in the first part of this article, now it is time to see in detail how we can use the Alphanumeric LCD Display in our Arduino sketches. The idea beside this project is to give a simple ...
