## Article

### **Project Summary**

This project aims at using the WIZ750SR Serial to Ethernet module from Wiznet for an IoT application of connected musical instruments with MIDI capability.

As a successful illustration, a digital piano (Casio CDP100) could be successfully controlled and polyphonic streams could be sent to the device using simple IP socket and threads implemented in Python, from both a PC as well as an android smartphone. A simple voice controlled application has also been designed and successfully tested with the device.

### **Hardware Design**

As part of this work, a basic hardware has been built (prototyped manually) as the design was simple to assemble and test manually.

However, a PCB module has also been designed in KiCAD and the Schematic, Layout and Gerber files have been shared as part of this project for prospective users if they would want to build a professional module as part of their designs.

Below is a snapshot of the manual prototype used in this project.
