It has a serious error.

The operating voltage of the GPIO pins is 3.3v with a maximum current draw of 16mA. This means that we can safely power one or two LEDs (Light Emitting Diodes) from a single GPIO pin, via a resistor.

The typical values for a 3 or 5mm LED is 1,8-3volt and 20mA depending on color and just one LED is over the maximum for the GPIO. So the statement in the article could potentially burn the GPIO pin!

Please correct the article.
