Descrição

Tilt switch module and a digital interface, built-in LED build a simple circuit to produce tilt warning lamp comes with digital interfaces of the LED, the tilt switch sensor interface to access digital 3, when the tilt open Off sensor senses a key signal, LED lights, otherwise off.———————————————–Example code———————————————-int Led = 13 ;// define LED Interfaceint buttonpin = 3; // define the tilt switch sensor interfacesint val ;// define numeric variables valvoid setup (){ pinMode (Led, OUTPUT) ;// define LED as output interface pinMode (buttonpin, INPUT) ;//define the output interface tilt switch sensor}void loop (){ val = digitalRead (buttonpin) ;// digital interface will be assigned a value of 3 to read val if (val == HIGH) //When the tilt sensor detects a signal when the switch, LED flashes { digitalWrite (Led, HIGH); } else { digitalWrite (Led, LOW); }}
