| Grove Light Sensor |
| ################## |
| |
| Overview |
| ******** |
| |
| This sample application gets the output of the grove light sensor and prints it to the console, in |
| units of lux, once every second. |
| |
| Requirements |
| ************ |
| |
| To use this sample, the following hardware is required: |
| |
| * A board with ADC support |
| * `Grove Light Sensor`_ |
| * `Grove Base Shield`_ |
| |
| Wiring |
| ****** |
| |
| The easiest way to connect the sensor is to connect it to a Grove shield on a board that supports |
| Arduino shields. Provide a devicetree overlay that specifies the sensor location. If using the |
| overlay provided for the sample, the sensor should be connected to A0 on the Grove shield. |
| |
| Building and Running |
| ******************** |
| |
| Build and flash the sample as follows, changing ``nrf52dk_nrf52832`` to your board: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/sensor/grove_light |
| :board: nrf52dk_nrf52832 |
| :goals: build flash |
