As a kid, I dreamed to build everything with LEGO, especially those could move and even form a robot. Sadly back in late 90's, the first generation Mindstorm was just way too expensive for me.
When I first met Arduino, I soon realized this could be a great alternative for Mindstorm controller. It even offers more possibility with the expandability. The remaining problem is how to put electronics and bricks together. So I decide to design some extension boards for Arduino to connect to LEGO painlessly, which is faya-nugget.
Here, I am going to show you how to build a controllable mini cooling fan with LEGO and faya-nugget.
Also, there's something we need to prepare for this project :D

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Get Started Wiring
Wiring: Module Pin ==> Arduino Pin
Firstly, the Stepper Motor module pins :
A ==> D11
B ==> D10
Ā (A-Bar) ==> D9
B (B-bar) ==> D8
Secondly, pins for 3V DC Motor :
(Caution) We use PWM for fan speed control, If you want to change the pin, please make sure you use a PWM pin.
3V motor SIG ==> D3
Finally, the Joystick!
VRX ==> V0
VRY ==> V1
Step 2: Wires Close Up
Step 3: Connect the Power Cords
All faya-nugget board has two power port (voltage-in and ground), the white tiny connectors as seen in the images, they are all parallel so you can connect them in the way you like.
Step 4: Power Up!
Final step of wiring, connect 5V (red) and GND (black) on Arduino board to any faya-nugget power port, and make sure every single board gets powered.
Step 5: Code Uploading
Give your creation a soul, use Arduino IDE to upload the code to your Arduino board.
If you are not sure what to do, you might want to check out Arudino's starter guide first:
Step 6: Stack the Bricks and Boards
In anyway you would like to! this is the best part, I will let you enjoy the moment.
Step 7: Work With Technic for Sure.
Step 8: Voilà!
You can get faya-nuggets on MCM Electronics: http://goo.gl/AVW2Im
I hope you enjoy this Instructable, and maybe you can share some idea with me too, Ciao!
