Arduino Nano 3.0 (ATmega328). Real Time Clock DS3231RTC. 32x8 LED Dot Matrix Display Module (with MAX7219 chip). LDR sensor.

We’re big fans of the impractical around here at Hackaday. Sure there’s a certain appeal to coming up with the most efficient method to accomplish your goal, the method that does exactly what it needs ...

The clock can be controlled with an app on your phone, a web page in a browser or with a serial cable connected to your PC, a rotary encoder, an IR-remote controller or (membrane) keypad. In Chrome, ...

Binary Clock is a clock that displays the current time in binary or decimal using a LED display. It really does not serve much of a practical purpose, unless your goal is to display the time in a ...

こちらのWiFi機能と12x8のLEDマトリックスを搭載しているArduinoのセットアップをします。 やりたいことは以下の3点です。 私の場合は、192.168.10.x（xは1~225）でした。家のWiFiにつながっているノートPCやスマホのIPアドレスを確認すると、192.168.10.101とか192.168.10 ...

There are LED clocks, and then there are LED clocks that can blind you from 30 paces. [Stiggalicious’s] LED ring clock is of the latter variety. 200 WS2812B/Neopixel RGB LEDs drive the ring clock to ...

I like this. Following on from the creative use of LEDs with the Periodic Table, check out this smart shelving system, similarly driven by an Arduino and using LEDs, that serves as a clock. Not a ...

今回は、Arduino UNO R4を使ってLEDを光らせる方法を解説します。 ELEGOOのLearningキットE3という電子工作キットを使った、初心者でも簡単に遊べるレシピです。 完成品のプログラムも載せているので、安心してください。 ぜひ、最後までチャレンジしてみて ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...
