Mood Lamp with Arduino

Hi! In this tutorial you will learn to make a mood lamp with Arduino.

I know that you may have seen a lot of mood lamp projects with Arduino, but I wasn't very satisfied with them because they all change the color very abruptly. So, I decided to make a smooth mood lamp and I also made it to turn on only when the room is dark.

This project is good for those who are beginners in the Arduino's world.

Step 1: What You Need?

1 x Arduino UNO
1 x USB Type-B Cable
1 x 9V Battery Holder  or  9V Battery Snap
1 x Breadboard  or  Mini Breadboard
1 x RGB LED  or  1 Red & 1 Green & 1 Blue LED
1 x LDR (Light Dependent Resistor)
Male-to-Male Jumper Wires
1 x Computer with Arduino IDE
1 x 9V Battery
1 x Sheet of paper

Optional
Other Color LED
USB To Power Jack Cable
Female-to-Male Jumper Wires

Don't have components? Don't worry. Just click the component's name. 

Step 2: Write The Code & Upload. 

Write the code above on the Arduino program.
Darker the ambient light is, the higher is the value read from the LDR.
I used PWM to change led's brightness.

  

Step 3: Build Your Circuit.

Connect wire like the schematic above.

Step 4: It's done!

Try to add a sheet of paper around it to see it more smoothly, the paper acts as a diffuser.
Feel free to modify this project to your way, and tell me your progress. Comments are welcome.
