CHNOPS BlobArt: Using an oscilloscope for value confirmation

[Jos Richters]

I use an oscilloscope (aka "scope") to investigate on the actual electric values that are generated by the studio.

Because the electric potential 3.3V that is put out by the ESP32 and the fact that the 100 KOhm resistors can differ slightly from the given values on their color codes I decided to connect a scope to the studio connectors.

This scope is able to measure two channels at once, so this is perfect to investigate on the real behaviour of the electric flow and power.

Below are two screenshots as they are derived from the scope's screen. (one of the many functions of this model)

This one shows the plain power output from the studio:

This one shows the power output where the maximal and minimal values are kept for five seconds giving a value range for both channels: color and opacity:

The light-gray squares are set to (vertical) 50 mV, so it can be seen that the values are approximately 100 mV for the yellow channel and 150 mV for the blue channel.
