红外通信是利用950nm近红外波段的红外线作为传递信息的媒体，即通信信道。发送端采用脉时调制（PPM）方式，将二进制数字信号调制成某一频率的脉冲序列，并驱动红外发射管以光脉冲的形式发送出去；接收端将接收到的光脉转换成电信号，再经过放大、滤波等处理后送给解调电路进行解调，还原为二进制数字信号后输出。-Infrared communication is the use of near infrared 950nm infra-red as the transmission of information media, namely communication channel. The sending end when the use of pulse modulation (PPM) approach will be a binary digital signal into a frequency modulation of the pulse sequence, and driver fired infrared tube to the form of light pulses sent receiver will receive the pulse of light conversion to electrical signals , and then, after amplification, filtering and other treatment to the demodulation circuit after demodulation, reduced to a binary digital signal after the output.

An "improved" inductance / capacitance meter Actually, it works much the same as the originalIt differs from the original in that: A 16F628 PIC is used. This has internal comparator, which means the LM311 is no longer needed.Software calibration is used. The finished meter can be calibrated against "any" accurate capacitor within the range 100pF to about 10000pF -An "improved" inductance/capacitance meter Actually, it works much the same as the originalIt differs from the original in that: A 16F628 PIC is used.
