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.
hisoka LED lamp Wow, cool post. I'd like to write like this too - taking time and real hard work to make a great article... but I put things off too much and never seem to get started. Thanks though.
Thanks for the comment
