analogWrite( 8, 182 );
would a transistor not be subject to the same issue with the modulating voltage supplied by PWM?
Should I use a couple of resistors to bring the cumulative voltage down to the expected 3.5v or will this not be an issue?
from what I've been reading transistors can be used as amplifiers
I did see a really nice project where a guy had built a single box that could be switched to trigger a camera based on sound or light, it was in a tough looking box so great for using 'in the field'
For this reason it is a good idea to connect OUTPUT pins to other devices with 470? or 1k resistors, unless maximum current draw from the pins is required for a particular application.
