Hi Silindile Makhanya,
I understand that you would like to create a pH neutralization system using Simulink and an Arduino Mega. This can be achieved by following the below steps:
- Installing Simulink Support Package for Arduino by > MATLAB > Add-Ons menu > Search for “Simulink Support Package for Arduino Hardware” > install.
- Below link provides information on installation of Simulink support package for Arduino
- Connect your Arduino Mega to your computer via USB.
- In Simulink, create a new model and add the “Arduino” block from the Simulink Library Browser.
- Designing the Control System in Simulink by creating the pH Neutralization Model, PI Controller and configure the PWM signal.
- Use the “Scope” block in Simulink to visualize the pH levels in real-time.
- You can control a mini plant for pH neutralization by setting up a feedback loop to adjust the dosing of reagents based on real-time pH measurements.
- Once the model is complete, you can deploy it to the Arduino Mega.
- Go to the “Deploy to Hardware” option in Simulink and select Arduino Mega.
Below link provides an example model of pH neutralization control
