说明：  红外无线遥控风扇+加速按-减速，默认最低速度，烧录后可以按遥控器上的“+”加速。4~9档区间可以电机不会转动，着可能是因为用户供电电流不足。1-4档在接线正确的情况下几乎都可以转动。 注意：测试时间最好不要超过1分钟，观察一下实验现象即可。
(Infrared wireless remote control fan + acceleration Press - deceleration, the default minimum speed, after burning, you can press "+" on the remote control to accelerate. The motor can not rotate in the range of 4-9, which may be due to the insufficient supply current of the user. Gears 1-4 can almost rotate when the wiring is correct. Note: the test time should not exceed 1 minute. Observe the experimental phenomenon.)
