Write an Arduino sketch to: 1)read the analog voltage output from the potentiometer through an ADC pin, then use this voltage reading to determine which sampling frequency to use for the following: 2)read the analog signal from the nScope through an ADC pin 3)send the resulting signal measurement over the serial port to be read by the VSA code on your computer 4)wait a defined number of milliseconds (or microseconds) before repeating the proces
