Experimenting with Arduino .1

Controlling Servo motor with potentiometer

(was able to control the rotation of the servo motor with precision)

Prepare to sleep

User physical intersection point

(Story board)

There is three physical intersection point 

-Turning on the bed side lamp

-Turning off the room light

-Turning off the room light after set up the bed and lie down

Pain points

-have to find the small lamp switch in dark environment

-twisting back to turn off the lamp light

--------------------------------------------------------------------------------------------------------------------------

Possible System Design

Concept IDEA - Automatic bedside lamp

current problem- user have to go back and forth to turn on the lamp light and turn off the room light.

by making the bedside light it makes user to go to bed without going back and forth to activate/deactivate the lights.

Arduino Input & Output

by using a photo resistor it was possible to activate the bed side lamp to turn on automatically according to light intensity 

Room light (off) -> Photo resistor detects light intensity (dark) -> Turn on the lamp

Input

User switch off the room light to go to bed (Room light off)

Output

Light on + Lamp cover open (motion)

--------------------------------------------------------------------------------------------------------------------------

Experimenting with Arduino .2

(controlling the rotation of the servo motor with photo resistor)



Input - Room light (off)
Output - Servo motor rotates according to the light intensity

this system can be  good solution for my product (lamp) so it's can be operated fully automatic so that user don't have to walk back and forth to turn on the lamp and turn off the room light  



the lighting can be also be included so motor and the light
moves & turns on at the same time

--------------------------------------------------------------------------------------------------------------------------


Experimenting with Arduino .3

(getting a feedback by using a ultrasonic sensor)

detects object/movement --- (Red light turns on) 

if there is not object/movements is detected --- (green light turns on)

- Will be a good option to add ultrasonic sensor to trigger the device so the light can be also turned on by user interaction (hand gesture)


- it can be good solution to provide better intersection with product
( User don't have to find the small switch button to turn on the light at night time )

Model Making .1

(Concept development)

Creating movement with Gears

( testing gear sizes & overall product sizes )

1:1 scale drawing for the gears

( possible internal layout - section view )

1:1 scale drawing for the gears and wings(covers)

(top view)

---------------------------------------------------------------------------------------------------------------------

Model Making .2

(Concept development)

1:1 scale cardboard model

(Gears, Wings)

Testing to see if the wing can close and open properly

Section view of the product (1:1 scale drawing)

CODING ARDUINO

                   

Photo resistor activates LED when surrounding gets dark

-

-

LED glows YELLOW

-

-

Servo motor rotates anti-clockwise

-

-

LED colour changes YELLOW to RED

-

-

Servo motor rotates clockwise

-

-

when movement is detected by ultrasonic sensor 

it activates the whole device again

-

-

when photo resistor detects enough light it shut down

the whole device

-

-

Serveo goes back to normal position

-

-

LED turns off

video file wasn't able to uploaded 
blog allows video size 100 MB max

(video size for interactive model 300 MB)

Model Making .3
(assembled 3D printed parts)

Fully functional 3D model

Servo motor/Photoresistor/ultrasonic sensor/LED

will be installed inside the interactive model

---------------------------------------------------------------------------------------------------------------------

Model Making .4
(assembled 3D printed parts with arduino)

When all 5 shells are attached, the servo motor wasn't able to provide enough power

to rotate the gear to open all 5 shells at the same time

Therefore all the shells were removed except one

Fully functioning

Manually rotating the shell to show the overall aesthetics and movement
