## Qrcode service
An echo service is nice, but not very useful. Let's create a more useful service
that generates QR codes. As of 2024-05-15 there doesn't exist a QR-code library
that is written in Toit, so we will use
that generates QR codes. We will use
Espressif's [qrcode](https://components.espressif.com/components/espressif/qrcode)
component that is written in C.

<Note>

These days you can generate QR codes directly in Toit with the
[qr](https://pkg.toit.io/package/github.com%2Flightbug-io%2Ftoit-qr) package, so
you would not normally reach for a C component just for this. We still use the C
`qrcode` component here because this tutorial is about communicating with C code,
and a QR-code generator makes for a realistic example.

</Note>

### Toit qrcode service
Create a new `toit-qrcode` directory next to the `echo` directory in the `components` folder.
