今回は電子工作ネタとして、低価格のArduino互換Wifiモジュール「esp8266」を使ってみたことについて書いていきたいと思います。今回はあくまでもテスト起動と言ったところですが、このモジュールを使うことで自宅のIoT化にむけていろいろと面白いことが ...

ESP8266 module (e.g., ESP-01, NodeMCU, or Wemos D1 Mini). USB to Serial adapter (for programming and debugging). Power supply (e.g., USB cable or batteries). Breadboard and jumper wires (if needed).

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 ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi with an ESP8266 ESP-01 module. With ...

Introduction This project is an ESP8266 WiFi Microphone firmware arduino source code (.ino) which can play live sound and voices with up to 80Kbps (10bit @8KHz ...

I have a wee major project underway - a giant clock made out of seven segment LED strips. Lots of soldering: Much to my surprise, the soldering all went fine and my Arduino code to display the time ...

Electronics is an expensive hobby. You often need to buy expensive hardware to complete a small hobby project. Fortunately, searching will give you a long list of cheap “retired” parts. If you’re sure ...

The maker, Rizwan's Ideas, made a video on DIY vacuum cleaner 3 years ago. A lot of people loved the original, but many wanted Wi-Fi and IoT features, so he decided to upgrade it with better tech and ...
