本设计以P89V51RD2FN单片机为电动小车的控制核心，采用MSA-LD2.0倾角传感器实时测量跷跷板的倾斜角，用ST198光电传感器检测黑色引导线监测小车运动。光电传感器和倾角传感器模块把实时测量信号馈送至单片机，利用专用细分芯片TA8435H驱动步进电机，以脉宽调制式斩波方式对步进电机步进角进行细分，控制和调节小车速度。采用增量式PID控制算法确保小车能够达到平衡；用RT128×64M液晶显示时间、角度等参数。经测试表明：小车各项性能指标达到设计要求，能够实现30秒内小车行驶到规定点，并保持跷跷板平衡；在跷跷板一端配重可调整的情况下，小车也能自动找到平衡点并保持跷跷板平衡。-The single-chip design for the electric car P89V51RD2FN control of the core, the MSA-LD2.0 seesaw angle sensor real-time measurement of the tilt angle, the detection of black ST198 photoelectric sensor to monitor vehicle movement and guide lines.Photoelectric sensors and angle sensors in real-time measurement module to feed the signal to the microcontroller, using a dedicated sub-chip stepper motor driver TA8435H to PWM chopper-type stepper motor on the sub-stepping angle, control and regulation vehicle speed. The use of incremental PID control algorithm to ensure that the car can achieve balance with LCD RT128 × 64M time, angle and other parameters.After the test showed that: the performance car

数字温度计进而考虑到用温度传感器，在单片机电路设计中，大多都是使用传感器，所以这是非常容易想到的，所以可以采用一只温度传感器DS18B20，此传感器，可以很容易直接读取被测温度值，进行转换，就可以满足设计要求。-Digital thermometer to take into account the use of temperature sensors, in single-chip circuit design, most of them are the use of sensors, so it is very easy to think of, so can use a temperature sensor DS18B20, this sensor can easily be directly read measured temperature values, the conversion, it can meet the design requirements.

万年历的完整算法:1900~2100 它首先计算出对应阳历月第一天对应是星期几，然后根据数据压缩算法确定， 确定对应的阴历日期； 而阴历节气，则有条件规律算法实现 这个万年历包括 阳历 阴历 星期对照 阴历 天干地支 生肖 -calendar integrity algorithm : 1900-2100 its first calculation of the corresponding solar calendar counterpart on the first day of the week. according to data compression algorithm to determine the date corresponding to the lunar calendar; and the cycle of the lunar calendar, it conditional law algorithm to achieve this calendar week including solar control the lunar calendar the Year of the lunar calendar Thus
