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。

I2C allows multiple devices to communicate using the same data lines. Each device is given an address code, and a controller device sends to and receives data from each device, using the address codes ...

Tilt sensors are essential components in security alarm systems today. Standalone tilt sensors sense tilt angle or movement. Tilt sensors can be implemented using mercury and roller ball technology, ...

The PIR motion sensor consists of 3 pins-VCC, GND, and the Data Output Pin. VCC is the power pin of the module. Out is the data Output pin of the module.it goes high when motion is detected. GND is ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

Arduino is a very popular open-source platform and Arduino UNO is one of the most loved microcontrollers among electronics hobbyists worldwide. It consists of a physical programmable circuit board and ...
