能完成对小车的往返，转向，速度的控制，小车能在慢速区慢跑，快速区快跑-completion of the car, from steering and speed control, the car will slow, jogging and rapid sprints District

可以将单片机与继电器以及温度传感器结合实现温度自动控制系统.例如可以用单片机显示温度传感器测到的温度,还可以在温度到达一定界限时控制继电器的通断以达到控制电路通断的效果.-Can be single-chip temperature sensor and relay, as well as realize automatic temperature control system combined. For example, we can use single-chip temperature sensor measured the temperature, but also the temperature has reached a certain limit of the on-off control relay control circuit in order to achieve on-off effect.
