MIDI-controlled actuation

With the press of a key on the MIDI keyboard, we have successfully accomplished mechanical motion from digital input.

The video above shows an early-stage prototype of our entire system functioning.

Our system software is the result of a carefully thought out design process. From start to finish, we have crafted each and every function to ensure it is as user-friendly as possible.

We have minimalized compatibility issues, effectively providing a smooth and seamless experience every time you use it.

Our PCB integrates three unique circuits together; isolating MIDI data from the user, parsing this data with a Nucleo F446RE microcontroller, and sending it off to the PLC.

This data is sent through a set of 4N26 optocouplers that electrically isolate our components from one another for protection purposes, and set the proper voltage and current levels for the PLC.
