Acquires data from the Arduino analog port, the 10 bit ADC.
The Arduino Uno has 6 analog ports (A0 to A5), the Arduino Mega has 16 such ports (A0 to A15). The block reads the value from an analog port (10 bit value from an Analog to Digital Converter (ADC).
The maximum frequency of acquisition for this block is approximately 125 Hz.
The port number 0 to 5 must be given for an Arduino UNO, 0 to 15 for an Arduino MEGA. There is no check on this value
The card number if several Arduinos are used. Must be 1 for the moment
The example below show the use of the block in case of a potentiometer with its middle pin is connected to analog port 2. The other 2 pins are connected to 5V and ground.
