In exemplul de mai jos am legat la un Arduino doua potentiometre si am facut capturi de ecran in timp ce le roteam de zor ;)

SimPlot Demo
Samples Analog Input and sends them over serial port to be plotted in SimPlot.
This Demo software uses the default serial port "Serial".
Upto to 4 channels of data can be plotted.
For details of SimPlot go to www.negtronics.com/simplot
Simplificata pentru postare pe blog - doua canale
Versiunea completa este la pagina de mai sus
