Descrição

Mercury switch module and a digital interface, built-in 13 LED build a simple circuit to produce tilt warning lamp 13 comes with digital interfaces of the LED, the mercury tilt switch sensor interface to access digital 3, when the tilt switch sensor senses a key signal, LED lights, otherwise off.SchematicArduino GND –> Pin – of moduleArduino 5+ –> Pin middel of moduleArduino 3 –> pin S of module———————————————————Example code———————————————————//KY017 Mercury open optical moduleint Led = 13 ;// define LED Interfaceint buttonpin = 3; // define the mercury tilt switch sensor interfaceint val ;// define numeric variables valvoid setup (){ pinMode (Led, OUTPUT) ;// define LED as output interface pinMode (buttonpin, INPUT) ;// define the mercury tilt switch sensor output interface}void loop (){ val = digitalRead (buttonpin) ;// read the values assigned to the digital interface 3 val if (val == HIGH) // When the mercury tilt switch sensor detects a signal, LED flashes { digitalWrite (Led, HIGH); } else { digitalWrite (Led, LOW); }}
