Introduction: LiFi: Transmit Music Using Light
In this instructable I will show you how to convert music to varying light intensity and then transmit it wireless using an LED and a solar cell whose output it seen by a speaker.
Step 1: Demonstration
Step 2: Parts Required
- 9V Battery
- Alligator wires
- Leds (here I use an emergency led light)
- Solar cell (Preferably above 2V)
- 3.5mm audio jack to be connected to mobile
Step 3: Transmitter & Receiver
Connect the 9v battery in series with the audio jack then connect it to the led.
The tip of the speaker jack is connected to positive of the solar cell and negative is connected to the body.
We have a be nice policy.
Please be positive and constructive.
