-The sensor for this lesson is a **sunlight sensor** that uses [photodiodes](https://wikipedia.org/wiki/Photodiode) to convert visible and infrared light to an electrical signal. This is an analog sensor that sends an integer value from 0 to 1,023 indicating a relative amount of light, but this can be used to calculate exact values in [lux](https://wikipedia.org/wiki/Lux) by taking data from the separate infrared and visible light sensors.

 1. Open the nightlight project in VS Code that you created in the previous part of this assignment, either running directly on the Pi or connected using the Remote SSH extension.
 
-1. Run the following command to install a pip package for working with the sunlight sensor:
-
-    ```sh
-    pip3 install seeed-python-si114x
-    ```
-
-    Not all the libraries for the Grove Sensors are installed with the Grove install script you used in an earlier lesson. Some need additional packages.
-
 1. Open the `app.py` file and remove all code from it
 
 1. Add the following code to the `app.py` file to import some required libraries:
 
     ```python
     import time
-    import seeed_si114x
+    from grove.grove_light_sensor_v1_2 import GroveLightSensor
     ```
 
     The `import time` statement imports the `time` module that will be used later in this assignment.
 
-    The `import seeed_si114x` statement imports the `seeed_si114x` module that has code to interact with the Grove sunlight sensor.
+    The `from grove.grove_light_sensor_v1_2 import GroveLightSensor` statement imports the `GroveLightSensor` from the Grove Python libraries. This library has code to interact with a Grove light sensor, and was installed globally during the Pi setup.
 
 1. Add the following code after the code above to create an instance of the class that manages the light sensor:
 
     ```python
-    light_sensor = seeed_si114x.grove_si114x()
+    light_sensor = GroveLightSensor(0)
     ```
 
-    The line `light_sensor = seeed_si114x.grove_si114x()` creates an instance of the `grove_si114x` sunlight sensor class.
+    The line `light_sensor = GroveLightSensor(0)` creates an instance of the `GroveLightSensor` class connecting to pin **A0** - the analog Grove pin that the light sensor is connected to.
 
 1. Add an infinite loop after the code above to poll the light sensor value and print it to the console:
 
     ```python
     while True:
-        light = light_sensor.ReadVisible
+        light = light_sensor.light
         print('Light level:', light)
     ```
 
-    This will read the current sunlight level on a scale of 0-1,023 using the `ReadVisible` property of the `grove_si114x` class. This value is then printed to the console.
+    This will read the current light level on a scale of 0-1,023 using the `light` property of the `GroveLightSensor` class. This property reads the analog value from the pin. This value is then printed to the console.
 
 1. Add a small sleep of one second at the end of the `loop` as the light levels don't need to be checked continuously. A sleep reduces the power consumption of the device.
