<p>2、连接后测试结果</p>
<p>2.1 本次测试连接了M1，使用5V电源转接，如下图。其中，首先用发光二极管代替电机测试连接状态，测试成功后再换电机连接。</p>
<p></p>
<p></p>
<p> </p>
<p>2.2 更改源代码，只留下和M1相关的代码，如下，</p>
<p></p>
<p>2.3 连接后显示视频结果如下。</p>
<p>使用发光二极管的测试结果</p>
<p></p>
<p>使用5V直流电机的效果如下。</p>
<p></p>
<p>这样的结果说明硬件运行良好，同时可以看到，使用这个扩展板，不需要再程序中使用扩展库，直接使用GPIO的模拟数字输出就可以。直接适用用于各种创客开发。</p>
<p>其中扩展板和主板之间电源接口是共用5V和GND地的。对于扩展板其实是2路供电，一路是控制电源，一路是驱动电机的电源，两者之间是不同用的。</p>

只能用Arduino吗？用GPIO该如何做呢?
<p>参照芯片手册，只是用数字0/1控制方向，模拟输出控制转速。任何MCU都可以的。</p>
