在代码中,我们必须先定义Reed开关和LED连接到Arduino的引脚。干簧管连接到Arduino的数字引脚4,LED通过限流电阻连接到Arduino的数字引脚7。变量“reed_status”用于保存干簧的状态。 int LED = 7; int reed_switch = 4; int reed_status; 复制代码 在setup()函数中,我们需要设置LED和干簧管连接的引脚状态。引脚4...

To test the response of the microphone I use the following sample code: /* Analog input, to trigger a flash by a reed switch Reads an analog input pin, prints the results to the Serial Monitor. Ted Kinsman emkpph@rit.edu */ // These constants won't change. They're used to giv...
12. Reed Switch A magnetic contact switch is basically a reed switch encased in a plastic shell so that you can easily apply them in a door, a window or a drawer to detect if the door is open or closed[click to continue reading…] ...

The SW-200D ball tilt switch must be soldered with the correct polarity for it to work with our Arduino program code. If you look closely, the terminal legs are of a different color. The leg which is slightly golden in color needs to be soldered nearer to the edge of the PCB. We ...
