Hi,
There can be 3 ways to control a stepper motor in MATLAB.
- Adafruit Motor Sheild. You can refer to this example for the implementation.
- Basic Arduino commands to control the motor in steps. (The speed will be slow)
a=arduino()
configurePin(a,'D2','DigitalOutput');
configurePin(a,'D3','DigitalOutput');
configurePin(a,'D4','DigitalOutput');
configurePin(a,'D5','DigitalOutput');
pins={'D2', 'D3', 'D4', 'D5'};
steps={'1100', '0110', '0011','1001'};
steps_size=size(steps,2); %steps = 4
for i = 1:100
step = steps{mod(i,steps_size)+1}; % step=1,2,3,4
for j=1:4
writeDigitalPin(a, pins{j}, str2double(step(j)));
end
%pause(0.01);
end
- Serial Communication (requires programming on the Arduino side)- You can setup a serial communication between Arduino and MATLAB. Depending upon the character sent by MATLAB to Arduino over Serial. The stepper can be programmed to move or stop.
