该项目旨在开发一个直流电机四象限控制系统。马达操作在四个象限，即顺时针旋转 ；逆时钟明智的正向制动和反向制动。直流电动机的四个象限运行是最适合工业 wheremotors 使用和按要求，他们可以在顺时针旋转，计数器顺时针旋转和也踩刹车立即在两个方向。第三十四条在工业环境中，bestopped 立即的电机需要特定的操作。在这种情况下，这项拟议系统是非常恰当的 asforward 刹车和反向制动是其积分功能。 瞬时刹车在这两个 directionshappens 由于反向电压跨运行电机申请一个短暂的时期。在项目中使用的 555 定时器的发展所需的脉冲。按钮提供的电机，连接到提供给它的输入的信号，并反过来控制驱动芯片 motorthrough 的循环操作。（可选） 速度控制功能可以实现 （但救生艇上不配备在此项目中） 由按钮操作。这个项目可以提高利用较高的电力电子装置对 operatehigh 容量的直流电机。也可以纳入再生制动优化的能耗。

Part IV In part II we discussed the conversion of binary numbers into decimal digits. It is sometimes useful to build circuits that use this method of representing decimal numbers, in which each decimal digit is represented using four bits. This scheme is known as the binary coded decimal (BCD) representation. As an example, the decimal value 59 is encoded in BCD form as 0101 1001. You are to design a circuit that adds two BCD digits. The inputs to the circuit are BCD numbers A and B, plus a carry-in, cin. The output should be a two-digit BCD sum S1S0. Note that the largest sum that needs to be handled by this circuit is S
