In the previous tutorial, we learned to blink LED by using the delay method. That method blocks Arduino from doing other tasks. In this tutorial, we are going to learn another method to blink LED without blocking other tasks. The detail instruction, code

When you plug the battery to Arduino Vin, it should work right away showing the voltage of your battery on your 16x2 LCD because Arduino is powered by that battery. If it is not working, please re-check your connection or the battery you use might be lower than 5 volts needed by Ardui...

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/...
