The experiment is for switching an acoustic sounder as a rain alarm after a predetermine time. It may, however, be tinkered for a number of other applications. Needless to say, this is a simple ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

This project is based on Arduino UNO and an ultrasonic sensor. It is designed to measure distance and trigger a buzzer if the measured distance is below a certain threshold. The ultrasonic sensor ...

Currently this library only supports the sensors mentioned above. If you want to use other distance sensors with this libraries you can do that by adding the appropriate source files. Have a look at ...

[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]’ ...

今回は、加速度センサからデータを取得して Arduino IDE のシリアルプロッタに表示させるスケッチを作りました。 とりあえずデータを表示できればいいから自分でちゃちゃっと描こうと考えていたのですが、当節は AI でコーディングするのが流行りとか。
