This is just to thank the DEV's for the serial plotter in 1.6.12
It gave me a very easy way to do a very simple test that I think anyone can do with just simply an Arduino board. Some boards are more responsive than others and CLONES are really good for this showing the difference in build quality.
Plug in your board.
Upload the example "AnalogReadSerial" sketch.
Start the Serial Plotter from the IDE Tools menu.
Just move your hand close to the boards and then away...
If the display scrolls to fast just increase the delay from 1 to about 10 in the sketch.
