Generally, a microcontroller (such as an arduino) can sink less than 100mA per pin. If that pin is driving 5V, then we see that it can provide (at maximum) only 0.05W of power. In order to provide more power, we need some additional circuitry. Think of it like a light sw… reference Wed, 03 Feb 2010 21:49:52 +0100
