This project uses an Arduino Uno and a sensor to count the number of objects passing by. The count is displayed on a 16x2 LCD screen. The system also includes a reset button to clear the count. The ...

IR Sensor get penetrate by motion of motor shaft, signal are transfer from IR Senor module to Arduino. This signal are processed in Arduino according to code loaded on it. Then Arduino transfer ...

下記の記事の続きです。前回の記事では、この取り組みの背景と温度及び湿度の計測機能の実装について書きました。この記事では、wifiモジュールによるIoTデバイス化と、MH-Z14Aによる二酸化炭素濃度計測機能の実装を行います。 Arduinoは単体でインターネットに接続できなかった さっそく計測 ...

今回は初めて電子工作の記事書きます。ArduinoとCO2センサーを使って二酸化炭素 (CO2)濃度測定器を作って、動かすところまでをやってみました。

[Todd Harrison] really has our number. Like him, we don’t want to spend money when we don’t have to, and hacking our own solutions is a lot more fun anyway. This time around he’s … ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

In this tutorial, we will learn to Guide you about how you can interface a heartbeat sensor with an Arduino to measure live-heartbeat of any person. We will be also interfacing an OLED display to the ...

Rain Drop Sensor acts as a switch when raindrops fall to the sensor, other than that with slight tweaks in the code it can also measure the intensity of the rainfall. We Interfaced the Rain sensor ...
