5PCS Hall Magnetic Standard Linear Module KY-024 For Arduino AVR PIC

Description

Product Overview
5PCS Hall Magnetic Standard Linear Module For Arduino AVR PIC
Product Descriptions
Linear Hall magnetic module and number 13 comes with LED build a simple circuit to produce magnetic field warning lamp. Use digital 13 interface comes with the LED. The linear Hall magnetic module connected digital 3 interfaces. When the linear Hall magnetic module senses detected the key signal. LED lights on, otherwise off.
Routines source code:
int Led = 13 ;// define LED Interface
int buttonpin = 3; // define the linear Hall magnetic sensor interface
int val ;// define numeric variables val
void setup()
{
pinMode(Led, OUTPUT) ;// define LED as output interface
pinMode(buttonpin, INPUT) ;// define linear Hall magnetic sensor as output interface
}
void loop ()
{
val = digitalRead(buttonpin) ;// digital interface will be assigned a value of 3 to read val
if(val == HIGH) // When the linear Hall magnetic sensor detects the signal, LED flashes
{
digitalWrite(Led, HIGH);
}
else
{
digitalWrite (Led, LOW);
}
}
