- Real-time Reading: The application continuously refreshes and displays the measured light intensity value.
- Configurable Gain: The user can easily adjust the sensor's gain, which allows for measurements in various lighting conditions, from very dim to very bright. Available options are: 1/8, 1/4, 1, and 2.
- I2C Address Change: The I2C address of the VEML7700 sensor can be configured.
- Simple Menu: Intuitive navigation using the Flipper Zero buttons (OK, arrows, Back).
- Flipper Zero device.
- VEML7700 ambient light sensor connected to the GPIO pins (I2C).
- Make sure the VEML7700 sensor is correctly connected to the Flipper Zero (I2C pins).
- Launch the application. By default, it will show the light intensity value.
- To go to the settings, press the OK button. In the settings menu, you can change the Gain and the I2C address.
- Use the left and right buttons (
$\leftarrow$ /$\rightarrow$) to change the values in the settings. - After changing the settings, the application will automatically re-initialize the sensor with the new configuration.
- To return to the main screen, press OK or Back.
- Press the Back button on the main screen to exit the application.
