1 将光敏电阻，面包板，Arduino拖入工作区，具体过程可以参考 2 要通过光敏电阻检测光线强弱变化就要用到Arduino的模拟量输入口。Arduino的模拟量输入口是检测模拟量的电压值，检测电压的范围是0到5V，然后进行AD转换，将0到5V转换成0到1023的数字。这样就需要将光敏电阻的阻值变化转换成电压变化才能被Arduino采集到。...
1 将Arduino,面包板，LED灯和电阻拖入工作区，将电阻阻值修改为360欧，将LED灯改为绿色，连接好线。选择6引脚来控制LED灯。具体过程可以参考 2 这个电路和Arduino控制LED灯闪烁的电路一样啊！是的，硬件电路完全一样，但是软件不一样就会得到一样的效果，这就是软件的神奇之处。0和1输出是采用digitalWrite()函数...

to change the speed of the LED chaser. The last part of the 555 timer is a electrolytic capacitor, which connects both pin 1 (ground) and pin 2. These are all of the main connections of the 555 timer. There is one last connection, but that brings us to the next component, the ...
