这是一个音量控制IC，采用IIC通信方式，容易控制，价格便宜。...

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.
