Green laser pointer experiment?

With the development and innovation of laser technology, green Laser pointer have made great progress. At the same time, professionals are also concerned about the practical application of laser pointers in our daily lives. Completed a series of experiments, just enjoyed the wonderful experience of the laser pointer. It is always fun to try a laser pointer. People can use a high-power green laser pointer to burn wood, matches or cigarettes, cut electrical tape, etc. For example, one should prepare a green laser pointer with an output power of at least 200mW, which is sufficient for thermal experiments. However, people still choose a 1000mW green laser pointer, or even a high-power output to burn wood or matches, in order to burn quickly in a short time.

Today we continue to use the electronic kit. This time we succeeded in generating and transmitting music with the help of laser. First, we built the receiver circuit based on the sketch in the manual. It was difficult for us to insert various resistors at the beginning because their color markings were not always very clear, so we confuse almost everything. Fortunately, in the end we finally had a clever idea (ironically) to simply measure various resistances with a multimeter to adjust some things in our circuit. The center part of the circuit is a photoresistor, and we aim the laser beam at it.
