I found a very nice toy of the case.
I was thinking trying to make a very nice clock with the toys of the case.

Unfortunately ,very nice toy of the case could not be found only one.
Failure is not allowed *_*

Step 1: Materials/components.

  • Very nice toy of the case × 1

  • Arduino Nano × 1

  • RTC (ZS-042)

  • 32 * 16 LED Matrix (AD-501-C:Rohm BD7851FP)

  • PHR10 cable 10cm (H2689-10cm-F41)

  • Electronic substrate

  • 2.54mm pin header female (10P + 6P + 15P +15P)

  • 2.54mm pin header male

  • USB Power cable (2-pin header)

Step 2: Design of Circuit Diagram.

RTC (ZS-042)

SDA pin -> Arduino Analog 4
SCL pin -> Arduino Analog 5

32 * 16 LED MATRIX AD-501-C:

1:VCC pin -> Arduino Degital 6

2:SIN1 pin -> Arduino Degital 7

3:SIN2 pin -> Arduino Degital 8

4:SIN3 pin -> Arduino Degital 9

5:CLOCK pin -> Arduino Degital 10

6:LATCH pin -> Arduino Degital 11

7:ENABLE pin -> Arduino Degital 12

8:VLED pin -> 5V

9:GND pin -> GND

10:GND pin -> GND

Step 3: To Create a PHR10 Cable.

Reconnect the 2.54mm pin header male to PHR10 cable.

.

Step 4: Temporary Assembly.

I have a provisional assembly by using a breadboard and a jumper pin , it was to create a Arduino sketch

of the clock.

Step 5: Time Adjustment.

Time adjustment is performed in the serial communication.

Step 6: Assembly.

I assembled as shown in the photograph.
It is completed and put into the case.

Step 7: Finally, Place It!

I was able my favorite watch.
I will put in place to see all the time :-)

<p>I love this project..thumbs up..how did u buy the 32x16 matrix ? does the website has English version ? also if you add seconds on the screen it would show more movement perhaps more eye catching.</p>
Thank you for your comment.<br>It is a very good idea to display the seconds.<br>I will try to improve in the next make watches.<br>I did not find it to investigate the English site that sells 32x16 LED MATRIX (+_+)
<p>i'll try, thanks for posting. </p>
<p>Good lock! :-)</p>
<p>Awesome clock.</p>
<p>Thank you for your very nice comments . </p><p>I am very happy.</p>
You did an excellent job. It was very smart to stick that LED matrix inside the glass case. Is that a display case for a model? You were very lucky it fit so perfectly. Congratulations.
<p>I appreciate your comments.</p><p>I'm so lucky(*^▽^*)</p><p>I found a case with Amazon.<br>It is the case that contained the dinosaur .</p><p>Case is reflected in the right rear of the second picture .</p><p><a href="http://www.amazon.co.jp/dp/B00J1J5NKS" style="">http://www.amazon.co.jp/dp/B00J1J5NKS</a></p>
<p>Very Nice. Will love to try it out.</p>
<p><b style="">Your words encouraged me.</b></p>
