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.

呢個係 DC 0-5V 錶頭
我一次淘左9個返黎
因為 0-5V 錶頭背板係分左 25 格，唔岩時間既 0-12 同 0-60
所以我就買多左一個分 30格既 DC 0-30V 錶頭返黎
SCAN 左個背板，再係電腦改返做 0-12 同 0-60

中間那段 hour PWM adjust, 用查表向法會否更簡潔及易維護些

在起始定義 adjMeterLevel 陣列

int adjMeterLevel[] = { 0, 21, 43, 65, 87, 108, 130, 152, 172, 192, 214, 234,
254, 21, 43, 65, 87, 108, 130, 152, 172, 192, 214, 234 };

在文內引用

if (lastMinute != minutes){
analogWrite(hoursMeter, adjMeterLevel[hours]);
....

c hing,即係個秒針可以好似機械表咁,不停地由左'掃'到右?咁去度59秒之後去番最左邊,其實由59秒去番1秒個個動作會唔會影響準確度?用wifi自動校準做唔做到呢?謝謝

作者: C_Law 時間: 2015-11-1 20:59

好有趣！

諗到個令秒針有小小鐘擺效果的玩法，但凡雙數秒就指到正，單數秒就加 N 秒，令秒針位置上升之餘有 N 秒來回擺動，例如 N =5：
真實秒數：00 01 02 03 04...57 58 59
秒針位置：00 06 02 08 04...62 58 64

不過會秒針最大位置會變成 64，要令 30 指到正中，秒針個錶的 Range 就要由 -4 到 64，要改過秒針個錶的刻度。

如果不改刻度，可以試下 30 秒前的單數秒 +N，單數秒超過 30 後就變 -N，雙數秒就一直維持指正。照舊 N =5 的話：
真實秒數：00 01 02 03 04...28 29 30 31 32...57 58 59
秒針位置：00 06 02 08 04...28 34 30 26 32...52 58 54

在 void printDate() 入面開頭加多個 Valuable：
int pSwing = 5;    //width of the pendulum's swing

再在原本的 228 行之前先檢查單數秒：
if (seconds % 2 == 1) { //odd second
  seconds = seconds + pSwing;
}
由於 228~232 的 if...else 已將秒針的 analogWrite 數值上限設定到 250(59s)，所以就算 seconds 加到超過 59，秒針都只會係去到 59。你亦可以試下改到上限為 255(60s)。

如果想在  30s 的時候改變擺動方向，可以在檢查單數秒之前再加上：
if ((seconds == 30) && (pSwing > 0)){
  pSwing = -pSwing;
}
