早前無意中睇到呢個，心血來潮馬上做返一個

Arduino nano + DS1307 RTC

用塊細萬用板就夠晒

DC 0- 5V 錶頭係萬惡既X寶買返黎，後來發現拆左入面粒電阻，改做 VR 會方便好多

木板都係响萬惡既X寶訂返黎，交張 CAD 圖比賣家，連激光切割只係60 人仔(一共做左三套)

開始砌模型，第一次出CAD圖訂木，唔記得計切割損耗，所以啲位有小小唔 FIT ，最後要出動 AA 膠

完成

經我修改既 Code，本身唔係好熟寫詩，有問題請多多指教

_____________________
Wiring goes as follows:
- USB red wire (5v) to VCC
- USB black wire to GND
- Buttons - Left/Down to Digital 2 (follow arduino tutorial: http://arduino.cc/en/uploads/Tutorial/button.png )
- Right/Up to Digital 4
- DS1307 RTC - SDA to Analog 4
- SCL to Analog 5
- Second Analog Meter to Digital 3 (PWM)
- Minute Analog Meter to Digital 6 (PWM)
- Hour Analog Meter to Digital 9 (PWM)
_______________________
Note:
Because all meters are slightly different, the PWM values
need to be adjusted based on your design. Feel free to use
my code, but you will have to change some values because
it is set to work specifically with my meters.
