This is a Toy Scope or a waveform display which i will integrate with my other tutors to display AC points in place of voltmeters.
Presently you can play with it. Power On and keep pressing the demo button give a few seconds between presses, to see all the waveforms stored. Tweak the four pots all you want, to understand something of this ancient electricity visualization apparatus.
Live Scope that can be operated
This scope "API" has few variables you can use in equation.
|xmov || x axis||horizontal value|
|h_pot|| x gain||horizontal gain or Attenuation|
|v_pot|| y gain||vertical gain or Attenuation|
