MINI reed switch moduleA reed module is a magnetic sensor that is normally open and get closed when exposed to a magnetic field.In our example turn off the buildin LED on pin 13 if the sensor is closed. For this you need to keep a magnet near the sensor.The module includes a 10 K Ohm resistor, so no additional parts needed.SchematicArduino GND –> Module pin -Arduino +5V –> Module PLUS (middle pin)Arduino Digital pin 3 –> Module S————————————————————–Example Code————————————————————-\/\/\/\/ Example code for sensor KY021\/\/ More info on ,http:\/\/tkkrlab.nl\/wiki\/Arduino_KY-021_Mini_magnetic_reed_modules\/\/int Led = 13 ;\/\/ define LED Interfaceint buttonpin = 3; \/\/ define the Reed sensor interfacesint val ;\/\/ define numeric variables valvoid 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); }}<\/p>\n","protected":false},"excerpt":{"rendered":"
