Creating A Variable Voltage Analog Signal WIth PWM And Variable Duty Cycle - Simply Put

A normal microporcessor (like what the Arcduino Uno uses) can't put out an analog voltage: The 'analogWrite' function is how you set a pin to PWM output mode, making it one of the most asinine function names in the history of software engineering. We can fix the mistake, though: A simple low-pass filter in the form of a resistor and a capacitor can smooth it out to an actual variable voltage, varying from low rail to high rail by varing the duty cycle from 0% to 100%.
