Clock With Life




one of the hardest thing is to create Relationship Between Human and electronics.

i think this clock is one good example for Relationship.

this clock is like new pet at house, he dosnt need you at all and he is playing with him self all the day

until someone is getting to close to 12 oclock.

this clock is hard to get and you will have to go to him to know what time is it.

Step 1: Components

1. arduino uno.

2.old scanner step motor or any other step motor.

3.ultra sonic sensor.

4.tiny rtc (real time clock).

5.peace of wood or any object.

6. dremel or any tool to fix the place for the motor.

7. 3d printer to create A clock hand.

Step 2: Wiring

the motor have 4 wire:

black : to pin number 8
yellow : to pin number 10
brown : to pin number 9
orange: to pin number 11

ultra sonic sensor
vcc : arduino 5v
gnd: arduino gnd
trig : to pin number 7
ecco: to pin number 6

tinyrtc RealTime Clock:
SDA :to pin number Analog4
SCL:to pin number Analog5

Step 3: Arduino Code

every step motor have step for full Round.
this code is for 97 step steps in a Round.
const int stepsPerRevolution = 97;

the speed is also change for one motor to another

    So, the clock is random until a hand approaches the clock. Then it shows the actual time? Not sure what you mean by "no one get close to 12 oclock. Could you expand on the relevance of 12 oclock please

    behind 12 oclock there is ultra sonic sensor,
    this sensor is calculate the distance.
    if your hand is getting close to 12 oclock and the distance<40cm
    then the clock will show the right time.

    hey Gruntbug.

    thanks for you comment.
    this clock has a "life" when he is alone and no one get close to 12 oclock with the hand he is doing randomize move.
    ones he detect an object (hand) is he showing you the time.
    its like having a cat its plays with him self until some one is coming home.
    The aim is to give life to inanimate objects.
    you have to get close and touch it to know what time is it.
