This course introduces you to Simulink by designing a basic LED blinking system. It covers:

• How to use Simulink to create models.
• Understanding and configuring blocks.
• Running simulations for LED control.

By the end of this course, you will understand how to create and simulate basic Simulink models.

This Simulink model simulates an LED blinking system on a Raspberry Pi. The model includes:

1. Pulse Generator: Creates a periodic signal.
2. Switch: Toggles the LED ON/OFF based on the signal.
3. Raspberry Pi LED Block: Represents the physical LED.
4. Scope: Visualizes the generated signal.

1. In MATLAB, click on the Simulink button in the toolbar.
2. Select Blank Model.

1. Open the Library Browser by clicking on the Library icon in the toolbar.
2. Drag and drop the following blocks:
   • Pulse Generator: Found under Simulink > Sources.
   • Switch: Found under Simulink > Signal Routing.
   • Raspberry Pi LED: Found under Simulink Support Package for Raspberry Pi Hardware.
   • Scope: Found under Simulink > Sinks.

1. Connect the Pulse Generator to the Switch.
2. Connect the Switch to the Raspberry Pi LED block.
3. Connect the output of the Pulse Generator to the Scope for signal visualization.

1. Double-click the Pulse Generator block:
   • Set Amplitude to 1.
   • Set Period (secs) to 1.
   • Click OK.
2. Double-click the Switch block:
   • Set the threshold value to 0.5.
   • Click OK.
3. Save the model: File > Save As, and name it BlinkLED.slx.

1. Click the Run button (green triangle) in the Simulink toolbar.
2. Observe the LED block toggling between ON and OFF states.
3. Open the Scope to view the pulse signal.

• Change the Period (secs) to 2.
• Observe how the blinking pattern changes.

• Duplicate the LED block and connect it to the same Switch output.
• Run the simulation and observe the behavior.
