AUTOMATIC NIGHT LAMP WITH ARDUINO AND LDR
In this project we have built an Arduino based automatic night-lamp using a LDR (light-dependent-resistor). A LDR is a type of light detector, when light falls on it, its resistance decreases and vice versa. By utilizing this property and a few basics about current division in branches, our device has been developed. This project can also be done without the Arduino UNO by using a BC547 transistor but in this project we basically want to demonstrate the interfacing of LDR with Arduino UNO and the relevant programming. The following video will demostrate the working of our device. LDR with cover-off LDR with cover-on Arduino IDE sketch
