The PWM signal in question is fed through a piezo speaker in parallel with a resistor. The output from the speaker is then sent to an FFT (fast fourier transform) app for Android devices ...
The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction of the input voltage. For a regulator, the pulse width will need to depend on the ...

Arduino Mega PWM Pins Explained: What Are They?Compared to the Uno, the Mega also comes complete with 15 PWM pins ... This variable output is achieved with the use of a square wave, which dictates how long the digital signal stays in the ...
It’s remarkable how many switching regulator chips use the same basic two-resistor network for output voltage programming ... useful if your application needs digital control of Vout via PWM. Figure 2 ...
