Reed module

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 (magnetic field change near the module), LED lights, otherwise off.

Example code 2 tested and working well with tutorial from: arduinolearning.com arduinolearning.com

Example 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 ()
SunFounder{
  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);
  }
}

Example code 2

from arduinolearning.com (working with the illustrated module and arduino uno clone)

// Arduino pin numbers
//D2 and A0 used on board and connected to D0 and A0 on the module
//G ground
//+ 5V
//open arduino console - upload the code and watch the result
 
const int digital = 2;
const int analog = 0;
 
void setup()
{
pinMode(digital, INPUT);
Serial.begin(115200);
}
 
void loop()
{
Serial.print(digitalRead(digital));
Serial.print("-");
Serial.println(analogRead(analog));
delay(250);
}
