I am now quite familiar with the arduino digital pins, input and output , using them for all kinds of cool things. I have also used an analog pin or two, much less so, simply reading in from an analog sensor
My current question, tho, is if I do not need the analog properties of the analog pins, can I simply use them the same as a digital pin? I only need 1-2 more pins for this project, and upgrading to a mega or adding a shift register seems like overkill.
Side question, if this works, does PWM work too or how does that relate?
