2 Stück Hall Magnetic Standard Linear Modul für Arduino AVR PIC Gut A2TM
Product Description 100% brand new and high quality 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 val.
