Bread board	yes	--	hard fibre	fixing and connections	30 mins
bevel gears	--	custom-made	plastic fibre	fixing them to rod and arranging them at 90 degrees	30 mins

Interaction aspect details

	Subsystem 1
	subsystem 2	subsystem 3
Energy interaction	No	Yes
Data interaction	Yes	No
Material interaction	Yes	Yes
spatial interaction	No	Yes

Explanation:

There is data interaction between subsystem 01 and subsystem 02 as there is passing of the commands for further process. Since there is usage of shoe,there exist material interaction.Between subsystem 01 and 03 supply of power is needed hence there is energy interaction and also there is transfer of liquid polisher for cleaning.Since the dimensions of the shoe are considered there exists spatial interaction between sub system 01 and 03.

Program

void setup

{

Serial.begin(9600);

pinmode(5,OUTPUT);

pinmode(6,OUTPUT);

}

void loop

{

int data==Serial.read()

if (data==1)

{

digitalWrite(5,HIGH);

digitalWrite(6,LOW);

}

}
