	This project aims to create a quartz crystal microbalance that can measure small masses (on the order of micrograms and below) for a start. The bigger goal would be to create one that can detect the thicknesses of thin films.

	In this project, we will use several LEDs as ~~Single Photon Avalanche Detectors (SPADs)~~. We will ~~use a light bulb as~~ the ~~light source~~ and ~~grating to vary the wavelength of~~ the light source~~. Thus, by knowing which light source is working for the LEDs to detect photons, we can determine band gaps of each LEDs~~.		In this project, we will use several LEDs as Photodiodes. When an LED receive light, it produces signal that we can detect. We will see the relation between currents that represent the signal and currents for the light source.
