KY-025 Reed Module Magnetic Reed Module for Arduino
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.
Routines source code:
int Led = 13 ;// define LED Interface
int buttonpin = 3; // define the Reed sensor interfaces
int val;// define numeric variables val
pinMode(Led, OUTPUT);// define LED as output interface
pinMode(buttonpin, INPUT);// output interface as defined Reed sensor
val = digitalRead(buttonpin) ;// digital interface will be assigned a value of 3 to read val
if(val == HIGH) // When the Reed sensor detects a signal, LED flashes
