A wireless communicator is made up of two different circuits. One the emitter side (side from where the laser is coming from), we have some of the most important components like the laser that is doing the data-transferring and input or audio-source. On the other side, we have the receiver circuit. The most important part of the receiver circuit is the LDR. An LDR or Light Detecting Resistor, as its name implies, reacts to the amount of light that is impacting it. Once both circuits are ready, an audio-source will be connected to the auxiliary cable running through the laser. Next, the audio that is being played by the audio source will change the laser's pulse towards a point where small, pulses occur. The laser's small pulses will be interpreted by the LDR and then translated to the speaker,which connected to the auxiliary cable on the output side,into a language it understands like 1 and 0's, also known as binary. Finally, the speaker will interprets thse 's and 0's and create what is for us sound.
Driving Question:
Is it possible to transfer sound through laser wirelessly into normal, analog speaker?
