Dawiinci:
It is simply the Blink sketch.

To "channel" raschemmel if I may, it is clearly not "simply" the "blink" sketch, as you are connecting it to something external to the Arduino.

To figure out the problem, we want to see your circuit, preferably a clearly focused photograph, correctly exposed in good lighting so that every detail can be followed, published using the "Additional options" on the "Post Reply" page in a resolution no larger than 1024 by 768 (and 800 by 600 will usually suffice if the photograph is clear).

In addition, the code you are actually using with this particular circuit, posted using the "code" tags (the [ # ] icon).

I saw that comin' a mile away....

We need a keyboard macro. :smiley:
