I need to know how I can control the amount of Serial.println(variable_1) methods that get read during the fscanf() execution.
This is the code:
arduino = serial('COM4');
fopen(arduino);
x = 1:1:60;
for i=1:length(x)
y(i) = fscanf(arduino, '%d');
end
fclose(arduino);
% Plot data from arduino
plot(x,y)
If my Arduino sketch has multiple Serial.println() it seems to combine the variables within the Serial statements in the same vector. Is it possible for them to be separated?

fscanf(arduino, '%d', 1);

y(i) = fscanf(arduino, '%d', 1);
z(i) = fscanf(arduino, '%d', 1);
if you want to read both of them. Or, more efficiently,
t = fscanf(arduino '%d%d', 1);
y(i) = t(1);
z(i) = t(2);

Thank you very much indeed. Much appreciated, will try that tomorrow.

How I can write data on my Arduino, after I read them in Matlab?
