A microcontroller can switch a voltage divider on and off by means of a suitable PNP transistor placed on the high-side of the circuit. If the voltage on the high side of the circuit exceeds the ...

Long Story:\nThis was written long before I learned to use version control. Hence the Clojure file mess. I first wrote the voltage divider in Python and a few weeks after learned rudiments of Clojure ...

By adding voltage dividers to the D+ and D- lines you can instruct the handheld to pull 1 Amp (with data voltages of 2.8v and 2.0v) for wall chargers or 0.5 Amps (2.0v on both data lines) for ...
