# Light Meter

## Overview & Parts

I recently needed to measure how different materials affect light transmission for a gardening project.  This seemed like a perfect fit for an Arduino project based around the TSL2561 Light sensor.

It can display the raw "Visible light" count from the sensor and then the calculated Lux.

I used the following parts in this project:

- [Arduino Uno](http://www.adafruit.com/products/50)
- [TSL2561 Digital Light Sensor](http://www.adafruit.com/products/439 "Link: http://www.adafruit.com/products/439")
- [16×2 LCD](http://www.adafruit.com/products/181 "Link: http://www.adafruit.com/products/181")
- [LCD I2C / SPI Backpack](http://www.adafruit.com/products/292 "Link: http://www.adafruit.com/products/292")

Optional (but definitely helps keep everything tidy):

- [Lady Ada’s Bento Box](http://www.adafruit.com/products/765 "Link: http://www.adafruit.com/products/765")
