Descrição

Linear Hall magnetic moduleLinear Hall magnetic module and a digital interface, built-in 13 LED build a simple circuit to produce a magnetic field warning lamp 13 comes with digital interfaces of the LED, the linear Hall sensor magnetometer access number 3 interface, when linear Hall magnetometer Sensor senses a key signal, LED lights, otherwise off. Example Code int Led = 13 ;/ / define LED Interfaceint buttonpin = 3; / / define the linear Hall magnetic sensor interfaceint val ;/ / define numeric variables valvoid setup (){pinMode (Led, OUTPUT) ;/ / define LED as output interfacepinMode (buttonpin, INPUT) ;/ / define linear Hall magnetic sensor output interface}void loop (){val = digitalRead (buttonpin) ;/ / digital interface will be assigned a value of 3 to read valif (val == HIGH) / / When the linear Hall sensor detects a magnetic signal, LED flashes{digitalWrite (Led, HIGH);}else{digitalWrite (Led, LOW);}}Powered by MediaWiki Powered by Semantic MediaWiki
