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 ...

Connect the A0 pin of the Arduino to the same column where the LDR and resistor is connected (Since the LDR gives out an analog voltage, it is connected to the analog input pin on the Arduino. The ...

At one end is an LED and at the other the LDR, and when attached to a glove it provides a finger sensor without the fuss. ... and with a simple divider circuit a voltage can be read by an Arduino.

The massive quantity of electricity gets used in lights through roadways in India. Still, roadways remain empty for nearly all of the day after at night, with a handful of cars passing during the ...

It uses an Arduino UNO which will handle all the processes acting as the brain of the system along with PIR and Vibration sensors to detect Anonymous activities ensuring full security from theft. LEDs ...
