Solar-Tracker-System-using-Arduino-and-LDR-Sensor Project Description Overview This project involves creating a sun-tracking system using servo motors and Light Dependent Resistors (LDRs). The system ...

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 ...

The amount of light reaching the LDR from the LED decreases as the pipe is bent, 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 ...
