This work has the main objective of developing a prototype of an electronic circuit that is intended to be eventually embedded into a commercial product used for dry fire practice. The prototype has two parts: a laser gun and a target. The main functionality of this prototype is to simulate a real gun, in such a way that it could be used by police officers and military to practice gun related skills in Brazil. For the development of the prototype, the method of opportunistic prototyping and opportunistic programming is used. The Arduino electronic development platform and the NRF24L01 wireless communication module are also used in this project. For the communication between the devices, it is used both the light emitted by the laser on the weapon and a light sensor on the target, as well as wireless communication for exchanging information between the weapon and the target. At the end of the project, a prototype of a functional device is presented, with a laser weapon that fires the light through the laser diode and a target that registers these shots through the LDR (Light Dependent Resistor) and counts both hits and misses on a 7-segment display.
