動機與介紹

由於先前勞基法修惡，也因此展開了一場勞方與資方之間的攻防戰。一邊是希望能早點下班，並且可以矇過資方。另一邊則是希望勞工超時工作之餘，並且可以躲避勞基法的追查。有鑑於此，本計畫僅提供一個專門對付打卡機的工具，搭載多種操作模式並可自動計算調整吾人上下班打卡時間的功能。

Arduino Time Recorder_Material

材料

■Arduino UNO 一片

■LCD 液晶顯示器(+I2C) 一個

■DS3231 時鐘模組 一個

■麵包板 一片

■LED燈 一盞

■1路繼電器模組 5V 一組

■擴充版 一片

■4ｘ4薄膜鍵盤 一片

Arduino Time Recorder_Modes of Time Recorder

■Clock Mode：顯示當前時間，也是此自動打卡機的主畫面。

■Check Mode ：強制打卡機完成打卡(手動操作)，不需等到自動打卡時間方可打卡作業。長按「*」完成，期間需耗時十秒。

■Schedule Mode：可查詢當日上下班的自動打卡時間。長按數字鍵「0」進入查詢， 再次長按則回到Clock Mode。

■Setting Mode： 調整日期與時間，長按「#」進入設定，0~9更改當前游標數 字，A、B、C、D分別為游標上下左右移動。

長按「*」取消更改，長按「#」確認更改。

上下班的打卡時間服從 Truncated normal

(因為常態分配為負無窮但正無窮，並且上下班要控制在一定時間，避免過早以及過晚到達。所以才設定為結尾的常態分配)

上班的分布: mu = 8:40 ; sigma^2 = 4 min ; Max = 8:50 ; Min = 8:30

下班的分布: mu = 18:15 ; sigma^2 = 4 min ; Max = 18:25 ; Min = 18:05

附圖左邊為使用R語言進行模擬的散布圖，右邊則是從Arduino收集來的資料。
