cmd_analog_in Command to read in analog signal from a connected Arduino board val = cmd_analog_in(h,pin_no) h : Board number, reserved for future use. For this version, any number would do pin_no : Analog pin to measure the signal val : Reading in the range of 0-1023 to to indicate the input voltage from 0-5V Arduino UNO board has 6 analog input ports (A0 to A5), the Arduino Mega board has 16 analog input ports (A0 to A15). The 10 bits channels convert the analog input from 0 to 5 volts, to a digital value between 0 and 1023. cmd_analog_in_volt Bruno JOFRET, Tan C.L.
