Gelsonlab HSTM-051 DIY Science Kit Electric Shooting การทดลอง

การทดลองยิงไฟฟ้า consists of a photoelectric control circuit composed of a photoelectric receiving tube and a laser light-emitting tube. When the photoelectric receiving tube receives a strong infrared laser, it is sent to the main control circuit U1 for processing, and then output to the horn to read out the voice of the laser gun hitting the receiving tube. Understand the principle and application of optical switch through experiment.
