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

1. fayaduino Uno (or you already have Uno)
2.faya-nugget stepper motor

3.faya-nugget DC motor

4.faya-nugget Joystick

5.Some Jump wires

6.2hours free time!

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!

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.
