In this short tutorial, we will show you how you can build yourself a transistor-driven color-changing RGB LED lights. The building process is simple and requires only a few transistors, capacitors ...

難易度を少し上げた電子回路として、「LDR（光抵抗）を使用した光センサー回路」を提案します。この回路は、光の強さに応じてLEDの点灯状態を変化させることができます。明るいとLEDが消灯し、暗いと点灯します。このプロジェクトは少し複雑ですが ...

An LED dimmer circuit adjusts the brightness of LED strips, serving both as an energy-saving tool and a method to create aesthetic lighting. Call bells, designed to draw attention, are commonly used ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components to a 555. But you needn’t go so fancy! [The Design Graveyard] explains how ...
