# MicroPython APDS-9960 Library
2+
3+
This library is a port of the [Python (and MicroPython) APDS-9960 Library](https://github.com/liske/python-apds9960/).
4+
5+
The examples could be easily tested with [mpremote](https://docs.micropython.org/en/latest/reference/mpremote.html) with the following command :
6+
7+
```sh
8+
mpremote mount . run examples/ambient_light.py
9+
```
