I suspect this should be in a different section, possibly the showcase section
Freelance developer and IT consultant


Very nice! But I think that is posted in the wrong place. As this is not a question you should post this kind of things in: "Community :: Exhibition / Gallery".

Hi shouldn't the LED on digital pin 13 (IC pin 19) have current limit resistor?

Without resistor what limits current for output?
Pin 13 cannot be used for anything because it is clamped by the LED volt drop.

The Contoller will, i.e. eventually it will die.
Put a resistor in series with the LED!
No technical PMs.
