Arduino Error: Too many output arguments

clear all;

a = arduino;

i=0;

while 1

pot=analogRead(a,0)

pot1=analogRead(a,1)

pot2=analogRead(a,2)

pot3=analogRead(a,3)

pot4=analogRead(a,4)

pause(0.5);

if pot4>700

s=servoWrite(a,'D11')

writePosition(s,0);

pause(0.5);

writePosition(s,0.5);

pause(0.5);

writePosition(s,1);

end

i=i+1;

pause(1);

end

Thanks in advance for your help and time!

The analogRead() method is not a part of the MATLAB Support Package for Arduino beyond release R2013b. For this, as a workaround you can use readVoltage method. It can be used for reading voltage from an analog pin on the Arduino hardware.

Also, please refer to the MATLAB answer attached below which might give you some idea: analogRead() for class arduino

Further, the servoWrite() method is also part of the legacy support package for Arduino. Using the servo method for connecting to the servo motor might resolve the issue for releases R2014b onwards:

s = servo(a,'D11');       % Using servo method for servo object creation
