cmd_analog_in_volt

Command to read in analog signal from a connected Arduino board

Parameters

h :

Board pointer, to indicate which board to use to differentiate one board from another

pin_no :

Analog pin to measure the signal

val :

Reading in the input voltage from 0-5V

Description

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. This function scale the reading to 0-5 so the user could get the measured voltage directly

Examples

h = open_serial(1,9,115200)
val = cmd_analog_in_volt(h,9)
close_serial(h)
