51单片机读写SD卡程序，经过测试，已在产品上使用-51 SCM SD card reader program, tested, used in products

本系统主要用于旅游景点记录游客人数，并限制旅客的流量。采用红外传感器通过检测人体红外并对通过人数进行计数，通过红外对管将检测到的数据发送至单片机，单片机处理后送至数码管显示，数码管显示的数据即为通过的人数，并通过设定值限制旅客数量。当游客超量是系统将给出相应的提示，禁止游客再进入。以更好的保护旅游景点的生态环境。-This system is mainly used for tourist attractions recording the number of visitors and limit the flow of tourists. Use of infrared sensors by detecting the human body by infrared and number of people count on the tube will be detected by infrared the data sent to the MCU, MCU after treatment sent to the digital LED display, digital LED display of the data shall be the number of through and through setting limits the number of passengers. When the visitors over-the system will give the appropriate prompts to prohibit visitors from re-entering. To better protect the tourist attractions of the ecological environment.

采用步进电机模拟洗衣机电机，实现上水、浸泡、洗涤、漂洗、甩干等过程。洗涤分弱洗、轻洗、强洗；可设定3级水位设定，每级水位均设定水位下限（值自定）；可选择漂洗次数（3~5次）。使用键盘进行流程及参数设定及自动存储流程，设定暂停键，可暂时停止洗衣机的工作，恢复后按原设定程序继续进行，同时设定停止键，可终止洗衣机的工作，并在LED或LCD上显示当前流程。-Simulation using stepper motors washing machine motor to achieve Sheung Shui, soaking, washing, rinsing, drying and other processes. Washing sub-weak wash, light wash, strong wash can be set to three water level settings, set the water level in each grade level were lower (the value of self-set) optional rinsing times (3 ~ 5 times). Using the keyboard processes and parameter settings and automatic memory processes, set pause button to temporarily suspend the work of washing machines and restore original settings after the process to continue at the same time set the stop button, may terminate the work of washing machines, and LED or the LCD displays the current process.
