The slot machine is a gaming device that simulates the operation of a slot machine. The project involves the use of electronic components and programming to create a functional gaming machine. The materials required for assembly include an Arduino Uno, enabling the development of electronic projects, an LCD display, consisting of a thin panel used to display electronic information such as text, images, and videos, and three push buttons. These buttons will be used to stop the game (left button), configure the difficulty level (middle button), and start the game (right button). It was also necessary to use a prototyping board, which has holes and internal connections for circuit assembly and is used to test electrical components. Other equipment includes jumper cables and wires, which are small conductors used to connect points in an electrical circuit, and a box or structure to house all the components.The physical assembly begins with connecting the LCD display to the Arduino Uno using jumper cables, following the display's pinout scheme. Next, we connect the three push buttons to the Arduino for the functions of "Stop," "Configure Level," and "Bet." Afterward, we assemble all the components in a box to create the cabinet of the slot machine.The game operates when the player places a bet using the "Bet" button. After the bet, the program checks for winning combinations on the reels. It is important to note that the player can stop the machine at any time by pressing the left button and configuring the level using the middle button.
