LilyPad Light Sensor Hookup Guide
The LilyPad Light Sensor is an e-textile friendly version of the Ambient Light Sensor Breakout. If you’ve used the breakout in a project before, the hookup and code will be very similar. You will need to connect to a LilyPad Arduino or other microcontroller to read the sensor values and use in your code.
This sensor outputs an analog value from 0 to 3.3V. In bright light (full daylight) this sensor will output 3.3V, and if completely covered will output 0V. In a typical indoor lighting situation, the sensor will output from around 1 to 2V.
To follow along with the code examples, we recommend:
To add this sensor to a project, you should be comfortable sewing with conductive thread and uploading code to your LilyPad Arduino. Here are some tutorials to review before working with this sensor:
