Visible light communication (VLC) is future technology for free space communication as well as underwater communication. This is due to the fact that the frequency spectrum of light in the visible range is useful for high-speed communication as well as large bandwidth. We demonstrate On-Off keying (OOK) modulation and demodulation of signal using blue LED and phosphor-converted LED (pc-LED) in Visible Light Communication (VLC). And their performance is computed in terms of SNR, pulse width and bit rate. Solar panel was used as detector in order to ease alignment-related complexities.
