2. Workshop Overview Matlab VS IDE Getting started
Hands-on Project 1: LED control
Hands-on Project 2: LED dimmer
Hands-on Project 3: Reading digital signal
Hands-on Project 4: Up counter
Hands-on Project 5: Reading analog signal
Hands-on Project 6: LED dimmer v2

3. Using MATLAB vs. IDE Environment1
MATLAB is more interactive, results from Digital/Analog I/O instructions can be seen immediately without needing to program – compile – upload – execute each time. It is a good idea even just for algorithm prototyping 2
For wider-breadth projects (that might include data
analysis, signal processing, calculations, simulation,
statistics, control design …) MATLAB is better suited

4. 1 2 MathWorks Solutions Arduino IO Package:
Used to perform analog and digital input and output as
well as motor control from the MATLAB command line 2
Arduino Target:
Used to compile and download Simulink® code directly to
the Arduino board

5. 1 2 3 Getting started Install Matlab 2012a or later version
Get arduinoIO package, unzip and place the folder inside a MATLAB folder :
C:\Program Files\MATLAB 3
Open pde folder. By using arduino IDE software, load adiosv.pde into your arduino

6. Getting started(cont.)4
Go to arduinoIO folder, copy everthing inside examples and simulink folder and paste it in the main arduinoIO folder
Paste here 5
Open the matlab software, change your current folder to ArduinoIO folder
ArduinoIO 6
Double click the arduino_io_lib.mdl file

7. Getting started(cont.)7
You should be able to see simulink library for the arduino IO package
Supported simulink block for arduino
ArduinoIO
Click to launch your first simulink example
example

8. Getting started(cont.)8
Your first arduino-simulink block
Click to start simulation
Your on-board led should blink once the program run.
Select your com port
Output to arduino led pin13

9. Hands-on Project 1: LED control
Prepare your simulink block:
Click library browser to view other simulink block
Click new to create new simulink model

10. Hands-on Project 1: LED control
Compulsory when using ArduinoIO package
Prepare your simulink block:
Drag and drop the required block to create new model
Can be obtained from simulink library browser

11. Hands-on Project 1: LED control2
Click to start simulation
Run your simulink model
Set to ‘inf’
This block will send digital signal 0 or 1 to arduino pin13.
When the simulation runs, double click to change the switching position and observe the LED on your board
