从键盘读入一个四位的十六进制数，CRT显示等值的二进制数. 由于每个十六进制数位对应4个二进制，所以每读入一个十六进制位后，即可将其对应的4个二进制位依次输出。由于数字‘０’~ ‘９’的ASCⅡ码为30H～39H,字母‘a’～‘f’与 ‘A’～‘F’的ASCⅡ码为61H～66H 与41H～46H ，因此，如果输入的字母为数字‘０’～‘９’，则其低４位即为对应的二进制位；如果输入的字符为字母‘ａ’～‘ｆ’或‘Ａ’～‘Ｆ’，则需要减７，然后通过移位将低４位依次输出。 -Reading from the keyboard into a 4 hexadecimal number, CRT display equivalent binary number. Since each hexadecimal number of the corresponding 4-bit binary, so every time into a hexadecimal places, can be its corresponding 4-bit binary sequence output. Due to the number

设计制作了一种智能台灯，主要是以BISS0001和单片机组成的红外传感控制电路。其特点是在有人时且外界光强较弱时能自动开灯，无人时关灯，节约能源；且能纠正坐姿，防止近视-Intelligent design a table lamp, and is based on single-chip component BISS0001 and infrared sensor control circuit. Its characteristics are in and the outside world when it was relatively weak light intensity can automatically turn on the lights when no one when the lights are turned off, energy conservation can correct posture and prevent myopia
