DARC decoder

With USB communications and a Scilab graphical user interface, we can really see what the PID controller is doing.

Part 3 in the “How to Make an Ambient Light Monitor” series. The project continues by building an ambient light sensor circuit on a breadboard, digitizing the circuit’s output signals, and interpreting the digitized measurements.

Delving further into the transmission line concept, the boundary between treating the line as a single lumped circuit element and using the distributed circuit parameters is investigated with a simple analysis in python. Circuit parameters for multiple waveguide geometries are shown.
