cmd_digital_out

Command to sent out digital signal to a connected Arduino board

Parameters

h :

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

pin_no :

Digital pin to sent the signal

val :

The value of 0 or 1 to be sent to the digital pins with. It is correspond to 0 and 5V

Description

The Arduino board has a set of logical ports (digital) that are used for writing or reading data from a component.

To map a UNO, ports 2-13 are available (0 and 1 are used for serial transmission). For MEGA board, ports 2-53 are available. The port takes the low logic level (0) or logic high (1) which corresponds to the reference voltage.

Examples

h = open_serial(1,9,115200)
cmd_digital_out(h,13,0)
sleep(1000)
cmd_digital_out(h,13,1)
sleep(1000)
close_serial(h)
