3.example
The example show that Reed module and the interface comes with digital 13 LED build a
simple circuit to produce a Reed warning lamp 13 comes with digital interfaces of the LED,
the Reed sensor access number 3 interface, when Reed sensors Sensed a key signal, LED
lights, otherwise off.
********Code Begin********
int Led = 13 ; / / define LED Interface
int buttonpin = 3; / / define the Reed sensor interfaces
int val ; / / define numeric variables val
