將數(shù)字時間轉(zhuǎn)換為英語口語表達形式，控制臺形式。其實核心代碼為一個類，可以自己修改輸出形式。 比如輸入 8 15 10 45 5 30 2 20 2 40 0 0 就能轉(zhuǎn)換為： It s twenty past eight It s a quarter past eight It s a quarter to eleven It s half past five It s twenty past two It s twenty to three 注意： 輸入 0 0 后結(jié)束并顯示結(jié)果 方式為每行兩個數(shù)，中間用空格空開 第一個數(shù)0到12表示小時，第二個數(shù)0到59表示分鐘

I can remember buying my first electronic calculator. I was teaching a graduate level statistics course and I had to have a calculator with a square root function. Back in the late 1960s, that was a pretty high-end requirement for a calculator. I managed to purchase one at the “educational discount price” of $149.95! Now, I look down at my desk at an ATmega2560 that is half the size for less than a quarter of the cost and think of all the possibilities built into that piece of hardware. I am amazed by what has happened to everything from toasters to car engines. Who-da-thunk-it 40 years ago?

該步進電機驅(qū)動器又稱為EasyDriver，EasyDriver能夠為兩級步進電機提供大約每相750mA（兩極一共1.5A）的驅(qū)動。它默認設置為8步細分模式（所以如果你的電機是每圈200步，你使用EasyDriver時默認為每圈1600步），更多細分模式可以通過將MS1或MS2兩個接腳接地進行設置。這是一種基于Allegro A3967驅(qū)動芯片的細分斷路器。對于此設計的完整規(guī)格，請查閱A3967的參數(shù)表。它的最大每相電流從150mA到750mA?？梢圆捎玫淖畲篁?qū)動電壓大概是30V，其中包括板載5V的調(diào)壓器，所以只需要一個電源。質(zhì)優(yōu)價廉，這玩意兒只要十幾美元，比你自己制作電路板更便宜。步進電機驅(qū)動器設計特色：· A3967 Microstepping Driver· MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)· Compatible with 4, 6, and 8 wire stepper motors of any voltage· Adjustable current control from 150mA/phase to 700mA/phase· Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds
