WARNING: I'm total noob, just playing around.
Converts Arduino PWM(5V) output to 0-3.3V analog.
Plan is to swap out a potmeter(5.2k) with the transistor in a remote control circuit(which controls a drone(CX-10) so I can control it through the Arduino). 220ohm resistance is the measured impedance of the MCU input.
Built and tested, reaction time is super slow but works(warning! peak 3.3V at 220 PWM).
Ardunio starter kit compatible. That's why I had to use a 100uF cap instead of a 10uF.
"Usage": Change the width of the digital input.
