Flicker up to 6 LEDs with Arduino

Hi there.
Christmas is coming closer, and I was wondering if I could put some candles in my room to get in the "christmas mood".
But after a friends house burned down of christmas tree candles, I don't want to burn real candles into my room.
So why don't let the Arduino light for you?!

This Instructable will show you, how to flicker up to 6 LEDs using an Arduino Microcontroller.
For more information about Arduino visit http://www.arduino.cc/

Step 1 What you need...

Here are the things you will need:

-Arduino Microcontroller (or similar)
-USB cable
-LEDs (up to 6 LEDs are possible)
-Resistors (equal to the number of used LEDs)
LED resistor calculator

if you don't want to solder the circuit:
-Breadboad
-Jumper wires

Optional:
-DC power source

Downloads:
-Arduino IDE
Get it here!

-TrueRandom Library
Get it here! (Instructions included)
Unzip it to your "Libraries" folder.

this i awesome keep it up

This was a great starter tutorial and introduction to Arduino. I'd like to slow down the randomness in the blinking, to make it look more like fire flies. Any suggestions on how to tweak the TrueRandom library to do this?

Hey,

thanks for the infromtation,but somehow i can't add the needed lines in the instructable.

For those wanting to use the code: put " "
after "#include"

Hi Gotcha,

Great little script. I am planning to use it to drive lights on a wreath. I noticed that you left out the library name in your include statement.

For those looking to duplicate this code, note that you need to download and install the TrueRandom library into your Arduino folders, then complete the include statement in the script as follows:

#include

the library can be found here:
