利用伟福Lab2000P单片机实验仪上显示电路，键盘电路，A/D变换电路，完成类似空调恒温控制实验，可以利用实验仪上的电位器模仿温度变化，加热和致冷电机可以用发光管代替。要求可以用键盘设定恒温温度，当外界温度超过设定温度+/-2℃时，就要启动加热或致冷电机。-Wei Fu Lab2000P use of single-chip experiment show circuit, keyboard circuit, A/D conversion circuit, the completion of a similar air-conditioning thermostat control experiment, the experimental apparatus can make use of the potentiometer mimic temperature changes, heating and refrigeration motors can be used light-emitting to replace. Requirements of the keyboard can be set thermostat temperature, when the outside temperature exceeds the set temperature+/-2 ℃, to start the heating or cooling motor.
