    I am doing project “Data Transmission using Li-Fi’. I need to transfer measured analog data using ADC and then converting into serial data format. I will be using LED to transmit data and I need to transmit the same in reverse also. I don’t know how to do it, please help me.

    Following are my suggestions.

    1. You can transmit data using similar technology that our IR remotes do.
    2. You can use an IR LED working under high frequency and you can use a TSOP sensor to decode it. For eg. 38KHz and TSOP1738
    3. For two way transmission you may set one device as master and another one as slave. Slave will transmit data only if it get a command from master. This will ensure that only one device will transmit at a time.
    4. You may also use two different frequencies. For eg. 30KHz, TSOP4830 and 56KHz, TSOP4856. In this case two devices can transmit data at the same time.
