****************************************
NOTE:
By turning the PR4 the voltage at analog pin # 4 changes and it causes the mode of the oscilloscope to change.
here are different modes :
Mode # 1 : 0-1.5V ===> Capturing one set of samples and showing them in a wide vertical range ( in this mode, the vertical shift feature is enable )
Mode # 2: 1.5v-3.3v ===> Capturing one set of samples and showing them on display with fixed rang ( the vertical shift is disable)
Mode #3 : 3.3v-5v ===> Capturing a set of samples every 100 ms and showing them on screen with fixed range.
To capture new samples in the modes # 1 and 2 the Arduino has to be restarted.
At the end, the switches number 1 and 2 must be disconnect while Arduino is receiving data from computer. the pins number 0 and 1 are used as TX and RX , so connecting them to LEDs interrupts the communication between PC and Arduino
The DC offset Switch is used to disconnect the PR5 from input line when a normal input is needed ( By connecting offset switch , the input range is changed from 0-5V to -5_+5 which can be adjusted with PR5) . Be aware that offset mode only work when in put is an AC signal.
