Arduino によるビニールハウス温度計測システムを作成しましたので、その内容についてご紹介します。 経緯とご注意 2019年頃に、Arduino R3 と「さくらのIoT」を組み合わせてビニールハウス温度計測システムの開発に着手し数年が経過しましたが、ようやく稼働 ...

でもまぁ16MHzのArduino R3ではこれが限界値ということで納得はできました。 USB電源ではそれなりにノイズはありますが、電池で駆動すれば残留ノイズは十分に低く、10ビットADC、サンプリングレート31.25kHzとは思えないくらいクリアです。

This is a thermometer based in Arduino UNO R3 with a DHT22 sensor and a 16x2 LCD screeen, also store the temperature and the humidity into the SD card. Shield-A v2.0 is Arduino Uno based shield for ...

If you’ve got an old black and white TV, it’s probably not useful for much. There are precious few analog broadcasters left ...

An intelligent trash can made using Arduino that detects motion around him, automatic opens the lid and signals when it is fully filled and must be emptied. An infrared sensor is used for motion ...

Abstract: This paper presents designing and implementing an Automatic room temperature control system using the Arduino and DHT11 sensor. The fan speed control system has also been proposed. Here, the ...

The Arduino UNO R4 brought a modern 32-bit platform to the UNO form factor. Arduino’s Alessandro Ranellucci explained the ...

The Arduino open-source development board is an immensely popular platform for engineers and makers to prototype their projects quickly. Its success and versatility is driven by its community, who has ...
