  • noise control car is Sunplus University plans to meet the 39
    音控小车是凌阳大学计划为配合61板的趣味性应用而推出的,以打破传统教育中学习单片机的枯燥性和低效性的现状为目的。此小车采用特定人识别,可通过语音命令对其行使状态进行控制,在小车前进过程中可自行躲避障碍物,为留给用户更大的发挥空间,在我们的电机控制板上留有开关型传感器扩展电路、PWM控制电路以及61板插接口和扩展电源接口,用户可根据自己的创意任意发挥。-noise control car is Sunplus University plans to meet the 39-61 plate application, launched the to break with the traditional education learning SCM boring and ineffective for the purpose of the status quo. This car used to identify a specific person, through voice command for the state to exercise its control, Trolley forward in the process may avoid obstacles, as users leave more room for a, in our motor control boards have expanded switch sensor circuit, PWM control circuit and 61 plate inserted interface and power supply expansion interface, users can own creativity arbitrary play.
