A Beginner Arduino Project: Tri Colour by a Bi Colour LED

Picture of A Beginner Arduino Project: Tri Colour by a Bi Colour LED
     Hi and welcome to my 7th instructable. This time I am playing with my new TRduino duemilanove. Actually it is a clone of Arduino made by Thinnkware and have ATMega 328.
     Arduino is a very good programmer and it is also open source(The thing I love about Arduino). We are making a Bi Colour LED to run three colours. You can see the video below on how it works. Enough talk, let's make it!

Step 1: Things you will need

1. Arduino with USB Cable(Any Arduino will work)( 29.9$
2. Bi colour LED ( 2.71$
3. Jumper wire( Wire): 5.99$
4. Breadboard($
Total: 48.59$

As my Arduino have male headers, I have to use breadboard and jumper wire. For those who have Arduino with female headers can directly connect LED to thier respective slot.

Step 2: Attaching LED

     First for those who don't know what is an Bi-Colour LED I am teaching it here. A Bi-Colour LED have two colour. See In the picture, the left-foremost pin is the red one which is bend from top. The right-foremost pin is the green one which is straight. The middle pin is Cathode means negative means minus means -. The two pin are Anode means positive means plus means +.
     OK, so attach the RED pin to 9th Digital pin of the Arduino. On Arduino, all digital pins are positive except two last pin after 13th pin.
Attach the green one to 10th and the middle one to Negative also known as GND.
     Now building part ends here, attach your Arduino via USB and open your Arduino IDE.

Thank you Sir
