Re: Variable power control
Take a look at this, http://www.toptechboy.com/arduino/lesson-8-writing-analog-voltages-in-arduino/
I am trying to figure out a way to use this inline with the PA power supply to be able to control the output power from software. Just brainstorming, but if you had a spare pwm pin and buffered its output with some capacitors into a transistor controlling the power rail, it might be doable. But I am really new to all this and am just looking at projects to try when my kit comes in.
Someone feel free to poke a hole in this and save me from wasting an afternoon if this isn't on the right track for a software controlled solution...
