LPA - The Light Plate Apparatus

The LPA is a device capable of illuminating each well of a 24-well plate with two independently time-varying light signals. An electronic board based on the Atmega328 microcontroller reads light intensity values from an SD card and controls the LEDs responsible for illumination.

This repository contains the source files needed to modify the LPA's design. To obtain the most recent files for building and using an LPA, visit the releases tab.

If you use the LPA in your research, please cite Gerhardt, et al. "An open-hardware platform for optogenetics and photobiology." Scientific Reports 6 (2016).
