In our previous post, we explored using the Solar panel + Led as a LiFi module. In this post, we shall be using IR sensors in order to transmit data (tones and square wave signals) wireless. The schematics of the setup are given below:
One can use this to send square wave of any frequency independently as well. This has been demonstrated in the video below
Watch the video demo for a live demonstration of the working of this concept.
This is not limited to tones, one can use it to transmit raw music as well.
