this is my very first instructables and I was referred by an old member. Follow her link here: (https://www.instructables.com/member/Analogue-Chick/)

Its a simple illustration on how we can connect Arduino to Matlab and actually control and get information on Arduino
using Matlab

I have seen few tutorials regarding how to control or get data from Arduino using Matlab. Matlab is a very powerful tool for student and engineers a like. That's why i want to create this tutorial as a start for those, like me want to explore the 2 powerful tools in engineering and techs.

It's a rough start for me since this is my first post in instructables.... feel free to comment so i can improve it thanks!

here's the vid for the demo:

Step 1: Step 1: Things You Need to Know

In this tutorial you need to know the following:
1. Matlab and creating M-file and GUI (there are tons of tutorials online)

2. Arduino and Arduino programming

3. Arduino Support with Matlab

tutorials from Giampiero Campa

Step 2: Step 2: Things You Need (materials)

1. PC with Matlab installed and the ArduinoIO package from MathWorks
2. Arduino
3. USB cable for the Arduino
4. LED
5. Photodiode (Photoresistor as an alternative)
6. Resistors

Step 3: Step 3: the Dreaded Process

For the Arduino:
1. Connect the circuit.
2. Connect your Arduino to your PC.
3. From the ArduinoIO (http://www.mathworks.com/academia/arduino-software/arduino-matlab.html)
upload the adiosrv.pde to your arduino. Now your arduino will be the server that will accepting commands
comming from Matlab.
For the Matlab
3. Run your Matlab as an administrator.
4. From the command window in Matlab type "install_arduino" (make sure that the active directory is in your ArduinoIO folder)
For this tutorial my idea is to make a manual and automatic lighting of an LED
5. Create an M-File in Matlab (or download below my GUI program). Make sure you have the right COM port of your Arduino)
(the yes.m.txt is the program source code, the yes.fig.txt is the GUI just remove the txt extension)
6. Run the program. Enjoy!
