How to put Arduino Uno to sleep mode using Simulink

I want to know what block I can use in Simulink to put my Arduino to sleep mode, but I can't quite work it out. I tried using a MatLab function block but it just showed me errors. Is there a block with which i can put it in sleep mode without manually writing code?

I am a beginner at this, any help would be appreciated. :)

There isn't any block in Simulink for the specific purpose of putting Arduino to sleep. This is because Simulink's built-in blocks do not directly support microcontroller-specific operations like sleep modes.

Hello @Bojan,

There is no built-in or direct block in Simulink for putting an Arduino into sleep mode. However, you can create your own custom block to achieve this functionality.

A highly effective approach is to use the "IO Device Builder" app, which is included in the "Simulink Support Package for Arduino Hardware." This app allows you to integrate custom or third-party C/C++ source files to create a System object, which then appears as a block in Simulink.

By using this app, you can create a block that leverages source files containing C++ or Arduino code to put the Arduino into low-power mode. You can then include this System object (block) in your model to control the Arduino’s power state.

For more details on the "IO Device Builder" app, you can refer to the following documentation page: https://www.mathworks.com/help/simulink/arduino-io-device-builder.html.

Additionally, here are a few tutorials to help you get started with the "IO Device Builder" app:
