Oscilloscope XY Art with Arduino

Follow up to using an Arduino Uno to draw a Christmas Tree on a Tektronix oscilloscope in XY mode.

This video looks into how the original sketch works and how the oscilloscope XY mode is used to draw graphics.

Along with the original tree graphic, there is a new decorated tree and a simple square box to illustrate the basic drawing method.

Using the Arduino, two PWM outputs with RC filters generate voltages that control the XY scope inputs, drawing simple pictures.
