println(pushBTN_state); delay(500); } Let’s break down the code to help you understand each part. We created two variables — push_btn_pin and pushBTN_state. push_btn_pin, which denotes digital pin 8 connected to the push-button in the circuit, stores the current value (state of...

This component can then be used anywhere in your HTML code simply by writing<hello-world></hello-world>. Note:Actually, our pushbutton requires just a bit more code: we need to declare an input property for the color, using the@property()decoractor (and with a default value of red), ...
