通过键盘设定温度和加热时间。 （2）使用DS18B20采集温度，采用七段数码管显示当前温度和剩余时间，并和设置的温度进行比较。 （3）当温度低于设定值时，通过DAC0832输出电压供给发热电阻RT1,使其温度升高。 -Through the keyboard setting temperature and heating time. (2) The use of DS18B20 collecting temperature, using seven-segment digital tube displays the current temperature and the remaining time, and and set the temperature for comparison. (3) When the temperature is below the set value, the DAC0832 output voltage of the supply of heat through the resistor RT1, so that temperature.
