Audio Laser : 5 Steps - Instructables

https://www.instructables.com/Audio-Laser/

Audio Laser: Music is stored on my mp3 player as magnetic patterns that are converted into vibrations of electrical current. In my headphone coils, these vibrations, in turn, create a vibrating magnetic field. Since there is a permanent magnet insid…

The laser needs to be turned off while the transmitter is scanning for the receiver, mainly for safety and power reasons. To achieve this, the 9V supply to the op-amp is controlled by an NPN transistor, which can act as a switch controlled by the microcontroller. Figure 2: Main transmitter circuit. Modulates laser amplitude based on audio input.
