NGT-501 : Bubble Maker
Creative Innovation SeriesCreative Innovation Series

Objective:
Using Arduino, Touch Button, DC Motor, and Step Motor to create a robot to blow
bubbles automatically.
Description:
An Arduino based bubble maker is created with a Touch Button, a DC Motor, and a
Step Motor. When user touch the Touch Button, the Step Motor move bubble wand
to soak in bubble water sink. After couple of seconds, the Step Motor aim the bubble
stick to DC Motor Fan to blow bubbles.
Module List:
1. UNO x 1
2. Arduino Interface Board x 1
3. Touch Button x 1
4. DC Motor x 1
5. Step Motor x 1

4. fayaduino UNO
1. Compatible to Arduino UNO
2. Use B-type USB interface

5. Arduino Interface Board
With Arduino Interface Board, you will be able to :
1. Firmly mount your UNO on brick plate
2. Bridge out the power from Arduino to other
faya modules.

6. Step Motor
1. Input step pulse at four phase A, B, /A, /B to control the distance, speed, and
direction of the Step Motor.
2. Rotor Step Angle (1-2Phase on) : 5.625°
3. Rotor Step Angle (1 Phase on ) : 1125
4. Gear Ratio : 64:1
5. LED A, B, /A, /B represents the status of corresponding phase being driven.

7. DC Motor
1. Input analog signal (DC voltage) at SIG port to control motor speed.
2. Input digital signal (HIGH/LOW) at DIR port to control motor direction.

8. Touch Button
1. The default signal at OUT port is Digital LOW.
2. Touch copper foil to generate Digital HIGH at OUT port.

9. Brick Set
1. LEGO brick compatible
2. Random color for each type
3. A bigger normal type brick maybe replaced by smaller brick
for example, a 2x4 brick maybe replaced by 2pcs of 2x2

11. Signal Wires
1. Signal Wire is used to connect signals between Arduino and faya module
pins.
2. The size of the signal wire is AWG22

12. B Type USB cable
1. Use B Tyep USB cable to connect between fayaduino UNO and
computer.

13. Brick Post / Fan Blade
1. Use brick post to interface faya
modules with bricks.
2. Brick post is stackable, as shown in
above pictures.
1. Install Fan Blade at shaft of DC motor

14. Power Wire
1. Power Wire is used to supply the power from one to another faya modules.
Red Wire connects to Vcc and Black Wire connects to Gnd.
2. Above example shows that the power from Arduino is delivered to DC motor
via Type A wire and delivered to other two modules via Type B wires.
Type A : Connector-to-Pins Type B : Connector-to-Connector
Type A
Type B Type B

15. Brick Plate
1. Use Brick Plate as foundation of the project.
2. Plate size : 32 x16
3. Random Color
