I found a solution (discussed in previous posts) that works for me on:

- W10
- W11
- Processing 4.4.7
- Processing 4.4.10

Code source:

_[teachablemachine-community/snippets/markdown/tiny\_image/tiny\_templates/TMConnector/TM\_Connector/TM\_Connector.pde at master · googlecreativelab/teachablemachine-community · GitHub](https://github.com/googlecreativelab/teachablemachine-community/blob/master/snippets/markdown/tiny_image/tiny_templates/TMConnector/TM_Connector/TM_Connector.pde)_

Changes made:

```auto
// Do not use:
//import javax.xml.bind.DatatypeConverter;

// Do not use:
//String data = DatatypeConverter.printBase64Binary(frameBuffer);

// Use this:
String data = Base64.getEncoder().encodeToString(frameBuffer);

```

Use a separate _Sketchbook folder_ and add only the libraries required:

The other libraries are included with Processing and do not have to be added.

I encourage you and your students to read the guidelines:

It’s a place to talk about general ideas and specific projects. You can learn more about the [Processing Foundation](https://processingfoundation.org/) on its website. Our goal is to promote software literacy within the visual arts, and visual literacy within technology-related fields — and to make these fields accessible to diverse communities.

The section on _Asking Questions_ may be helpful!

I will assist you if follow the guidelines with future questions and only work with Processing 4.4.7 or the latest Processing 4.4.10.

Have fun!
