Descrição

When the key is pressed the buildin LED on pin 13 will be turned off.Connecting to the ArduinoPin – = GND, connect to GND of the ArduinoPin (middel pin) +5 v, connect to Arduino +5Pin S signal, connect to Arduino pin 10———————————-Example code———————————–int Led = 13 ;// define LED Interfaceint buttonpin = 10; // define the key switch sensor interfaceint val ;// define numeric variables valvoid setup (){ pinMode (Led, OUTPUT); // define LED as output interface pinMode (buttonpin, INPUT); // define the key switch sensor output interface}void loop (){ val = digitalRead (buttonpin); // digital interface will be assigned a value of 3 to read val if (val == HIGH) // When the key switch when the sensor detects a signal, LED flashes { digitalWrite (Led, HIGH); } else { digitalWrite (Led, LOW); }}
