RGB LED connections to NodeMCU ---> connect the negative of LED to ground and the other lines of LED to three digital pins ,say D1,D3,D5,of the NodeMCU.Similarly connect the other RGB LED to the ...

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 ...

Welcome to the Light Following Robot project repository! This project demonstrates how to build a simple yet effective light-following robot using Arduino and Light Dependent Resistors (LDRs). This ...

You’re asking what is LDR? It stands for Light Dependent Resistor or Photoresistor, which is a passive electronic component, basically a resistor which has a resistance that varies depending of the ...

When most of us think of glove controllers, the first which comes to mind is Nintendo’s PowerGlove, which promised much more than it delivered. But the idea persists, and from time to time we see them ...

This musical light alarm circuit is very simple, uses only 7 components, a LDR and a 3.6 V battery or 3 x 1.2 volts rechargeable batteries. The well-known UM66 is used as the sound generator and will ...
