#include <Pin.h> // Include Pin Library
Pin myPin = Pin(13); // Create Pin object for digital pin labelled 13 on any of the supported boards
void setup() {
myPin.setOutput(); // Set Pin to output
}
void loop() {
while(true) {
myPin.setHigh(); // Set Pin to output HIGH
myPin.setLow(); // Set Pin to output LOW
}
