A New laser pointer app
A mobile phone with a laser pointer function application program and an implementation method thereof. The mobile phone includes a light-emitting diode provided with a laser teaching pen on a housing, and is connected to a first circuit loop controlled by a first switch; Is the first MOS tube, which is set in the first circuit loop; the gate of the first MOS tube is connected to the first output port of the GPIO pin of the mobile phone baseband chip; the first circuit loop is located on the circuit board inside the housing, and the first The circuit loop is connected to the battery of the mobile phone. Since the first MOS tube associated with the baseband chip is used as the switch on the mobile phone, the level signal output from the first output port of the GPIO pin of the baseband chip is used to turn on the first MOS tube, thereby closing the first circuit loop and lighting up As the light-emitting diode of the laser teaching pen performs teaching, a non-key laser pointer function is realized on the mobile phone, which avoids reducing the requirements on the appearance of the mobile phone due to the provision of buttons on the casing of the mobile phone.

Technology
This laser pointer mobile phone equipped with a laser application program that emits a laser beam is characterized by installing a laser pointer on an ordinary Laser pointer mobile phone. The main devices include: laser diode, transformer unit, luminous power adjustment unit, control device, and color Filter lens. The luminous power of the laser diode is less than 5mw, the laser wavelength is less than 800nm, and the effective irradiation distance of the emitted laser beam can reach 200M. The user turns on the laser switch and adjusts its luminous power through the basic buttons on the laser pointer mobile phone, and obtains laser beams of different colors through the movable filter lens. The laser pointer shares the power supply of the laser pointer mobile phone, and can be designed and installed on any part of the laser pointer mobile phone, so that the user can indicate the remote target position when needed.
