PWM电机驱动模块接口，通过定时模块产生PWM波驱动直流电机工作，如果你手头上没有直流电机，你可以测量一下uln2003的输入口波形，如果你有直流电机，需要在uln2003输出接口上外接上拉电阻到电源，组成你的电机驱动模块。
-PWM motor drive module interface, through the regular wave PWM modules have a DC motor-driven work, if you do not have the DC motor, you can measure some of the input waveform uln2003, if you have a DC motor, the need for external interface uln2003 output pull- resistance to the power supply, the composition of your motor drive module.
