An easy to use Arduino library for fast and simultaneous operations on Arduino I/O pins.
Pin-Toggle.ino
#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 mode
myPin.setHigh(); // Set Pin to output high
}
void loop() {
myPin.toggleState(); // Set Pin to output the opposite of the previous output (HIGH -> LOW, LOW -> HIGH)
delay(200); // Wait 200 milliseconds
}
