This system uses a colour-changing LED (RGB LED/tri-colour LED) that switches to a new colour every 5 seconds. Simultaneously, the colour name is displayed on an OLED mini screen (SSD1306). This ...

This is a tiny and clearly arranged Arduino library for the basic RGB LED functions, to easily drive an RGB color LED (common anode/common cathode) and mix the colors. It uses the principle of ...

本プロジェクトは、受動型赤外線センサー（PIR）を使用して観客の存在に反応する、IoTベースのインタラクティブランプの開発を目指しています。このシステムは、Arduino Unoを主制御装置として使用し、視覚効果を提供するRGB LEDと動きを検出するPIRセンサー ...

A pet project built to explore how a browser-based UI can communicate with physical hardware in real time. The idea was simple: pick a color on screen and have an RGB LED reproduce it instantly — no ...

In Arduino, an RGB LED is a special type of LED that can produce various colors by adjusting the brightness of the red (R), green (G), and blue (B) components. The RGB color model includes these three ...

Among quantitative analysis techniques, molecular absorption methods in the ultraviolet/visible region are the most commonly employed in chemical laboratories worldwide. In general, the absorbance ...
