I am having trouble setting up a while loop in Matlab that will interact with LED's on an arduino board that has already had a program uploaded to it. I keep receiving error messages in command:
>> Modified_Fortune Press 1, 2, 3, or 4: 1 Press 1, 2, 3, or 4: 2 Error using serial/fwrite (line 199) Unsuccessful write: OBJ must be connected to the hardware with FOPEN.
Error in Modified_Fortune (line 13) fwrite(s,'1'); %activates pin 12 on arduino board
HERE'S MY CODE WITH SCREENSHOTS AT THE END:
delete(instrfind({'Port'},{'COM3'})) clear all; s=serial('COM3'); fopen(s);
while 1 a=input('Press 1, 2, 3, or 4: ', 's'); fwrite(s,'1'); %activates pin 12 on arduino board fwrite(s,'2');%activates pin 13 on arduino board fwrite(s,'3');%activates pin 15 on arduino board fwrite(s,'4');%activates the channel 12,13,15 on arduino board. fclose(s); end
And the following pictures are my Arduino code:
