Instead, we utilize the millis() function to manage timestamps effectively. For beginners, managing timestamps while blinking multiple LEDs can be challenging. Fortunately, the ezLED library simplifies this process by internally handling timestamp management. This removes the burden of managing time...
The best thing to do is get it working in the IDE, and then move it out to your own system. > So is that file there, and not supposed to be used anywhere? That file should be in “hardware/mighty-1284p/variants/standard”. The file you’re picking up is in “hardware/arduino/...
Let’s be very clear: when millis() rolls over, your Arduino will not lock up. In fact the Arduino’s ATmega processors very rarely lock up. So no, when the millis() value rolls over to 0, your Arduino won’t lock up and your project won’t explode. Ok? [Editor’s Note: If ...
