Light sensor Dark sensor. Light and dark detection using an LDR. For this project, let’s stick to the LDR sensor module so we can select the light or dark detection by placing jumpers. We’ll be using ...

Hi Everyone, This is my 1st Arduino's tutorial video. In this video i am going to show you how to use a LDR or Light Dependent resistor to turn on and off another circuit or a LED. Wouldn’t it be ...

Este projeto demonstra como usar um resistor dependente de luz (LDR) como um sensor para medir a luz ambiente e controlar um LED de acordo. O código Arduino lê o valor analógico do LDR e o mapeia para ...

At one end is an LED and at the other the LDR, ... and with a simple divider circuit a voltage can be read by an Arduino. ... but using another LED as the light sensor. Closeup of the sensor: ...
