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
void setup()
{
pinMode(Led, OUTPUT);// define LED as output interface
pinMode(buttonpin, INPUT);// output interface as defined Reed sensor
}
void loop()
{
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
{
digitalWrite(Led, HIGH);
}
else
{
digitalWrite(Led, LOW);
}
