[0032] Please also refer to Figure 3 and Figure 4 In this embodiment, the main control chip 20 includes 24 pins, of which the 12th pin is a ground pin. The 11th pin is a power input terminal 21 (VBAT terminal), which is connected to a capacitor and then grounded. The 10th pin is a power output terminal 22 (VDDIO terminal), which is connected to a capacitor and then grounded. The 5th pin is a first communication terminal 23, which is connected to the light control chip 30 for communication. The 13th and 14th pins are audio control terminals 24, which are connected to an external audio playback device 400 (such as a speaker, etc.) and are used to control the audio playback device 400 to play audio information. The 9th pin is a switch control terminal 25, which is connected to the switch unit 500 and is used to control the main control chip 20 to perform operations such as turning on or off the power, adjusting the volume, switching the game mode, etc. The remaining 16 pins of the main control chip 20 are input control terminals 26, which are connected to the input unit 200, so that the main control chip 20 can receive the player's game operation information through the input unit 200. Obviously, in other embodiments of the present invention, the number of pins of the main control chip 20 can also be adaptively adjusted according to the number of the input control terminals 26 and the presence or absence of the audio control terminals 24 .

[0033] In this embodiment, the light control chip 30 includes 24 pins, of which the 12th pin is a ground pin. The 10th and 11th pins are the power supply terminal 31 (VDD terminal), which is grounded after being connected to a capacitor. The 15th pin is the second communication terminal 32, which is connected to the first communication terminal 23, so that signal communication can be performed between the main control chip 20 and the light control chip 30. The 1st-9th and 18th-24th pins are the first power supply control terminal 33, which is connected to the light unit 300 and is used to control the lighting or extinguishing of the light unit 300. The 13th-14th and 17th pins are the second power supply control terminal 34, which is connected to the light unit 300 and is used to control the color of the light emitted by the light unit 300. Obviously, in other embodiments of the utility model, the number of pins of the light control chip 30 can also be adaptively adjusted according to the number of the first power supply control terminal 33 and the second power supply control terminal 34.

[0034] In this embodiment, the input unit 200 includes sixteen keys 40 (KEY1-16) and a direction control member 50, wherein the sum of the number of keys 40 and the direction control member 50 is equal to the number of input control terminals 26. The number of keys 40 is the same as the first power supply control terminal 33, and the multiple keys 40 and the direction control member 50 are connected to the multiple input control terminals 26 in a one-to-one correspondence. Specifically, one end of the sixteen keys 40 is respectively connected to the sixteen input control terminals 26, the other end of the sixteen keys 40 is grounded, and the multiple control keys of the direction control member 50 are connected in parallel to another input control terminal 26. When each key 40 is pressed or touched, a pressing signal is sent, so that the main control chip 20 can notify the light control chip 30 to change the lighting state of the corresponding light-emitting unit 300 according to the pressing signal. Obviously, in other embodiments of the utility model, the number of keys 40 can also be adjusted to other positive integers greater than or equal to two, and the number of direction control members 50 can also be adjusted to more than two.

[0035] In this embodiment, the direction control member 50 is a rocker, and the rocker has a first direction control key 51, a second direction control key 52, a third direction control key 53 and a fourth direction control key 54. The connection mode of the above four direction control keys is specifically that one end of the first direction control key 51 is connected to an input control terminal 26 and is connected to the power output terminal 22 through a first resistor (R1), the other end of the first direction control key 51 is grounded, the second direction control key 52 is connected in parallel with the first direction control key 51 through a second resistor (R2), the third direction control key 53 is connected in parallel with the first direction control key 51 through a third resistor (R3), and the fourth direction control key 54 is connected in parallel with the first direction control key 51 through a fourth resistor (R4). The player controls the direction control member 50 to swing in different directions to trigger the direction control keys of the corresponding directions to send direction signals, so that the main control chip 20 can notify the light control chip 30 to change the position state of the corresponding light-emitting unit 300 according to the direction signal. Obviously, in other embodiments of the present invention, the direction control member 50 may also be a key combination formed by connecting multiple direction keys, and the direction control member 50 may also have one, two, three or more than five direction control keys.

[0036] The lighting unit 300 includes a plurality of indicator lights 60. In this embodiment, the number of the indicator lights 60 is the same as the number of the buttons 40 and is respectively arranged corresponding to the position of the buttons 40. The number of the indicator lights 60 is sixteen and each indicator light 60 is an RGBLED lamp bead. Since the RGBLED lamp bead is used in this embodiment, one end of each indicator light 60 is connected to a first power supply control terminal 33, and the other end of each indicator light 60 is respectively connected to a plurality of second power supply control terminals 34. At this time, the number of the second power supply control terminals 34 is three and they are respectively a blue light emitting signal output terminal, a green light emitting signal output terminal and a red light emitting signal output terminal. The red light emitting signal output terminal is connected to the plurality of indicator lights 60 through a diode (D), wherein the diode plays a role of voltage reduction protection. It can be understood that the light control chip 30 controls each indicator light 60 to turn off or emit a color of light through the first power supply control terminal 33 and the second power supply control terminal 34 at the same time. The player can operate the button 40 or the direction control member 50 to play the game according to the lighting state of each indicator light 60.

[0037] In other embodiments of the present invention, the number of indicator lights 60 may also be a multiple of the number of buttons 40, such as two times, three times, etc. Each indicator light can emit light of at least one color, for example, it may be a single-color LED lamp bead or a dual-color LED lamp bead, etc. The number of colors is the same as the number of the second power supply control terminals 34, and multiple indicator lights corresponding to one color are connected to multiple first power supply control terminals 33 in a one-to-one correspondence and then connected in parallel to a second power supply control terminal 34, and at least one indicator light of one color is connected to the second power supply control terminal 34 through a diode.

[0038] Based on the connection settings of the main control chip 20, the light control chip 30, the input unit 200 and the light unit 300, the control circuit provided in this embodiment is provided with at least seven game modes. The first game mode can be a whack-a-mole mode, in which the light control chip 30 controls at least one indicator light 60 to light up a light of a random color at a time, and the player needs to press or touch the corresponding button 40 to turn off the lights of other colors except a specific color (such as red) during the game. In the process of the light control chip 30 continuously controlling the indicator light 60 to light up multiple times, the indicator light 60 at the same position can be controlled to light up lights of different colors. When the main control chip 20 detects that the corresponding button 40 is pressed or touched, it determines that the game continues, and when the main control chip 20 detects that the button 40 corresponding to the specific color is pressed or touched, it determines that the game fails.

[0039] The second game mode can be an extreme speed obstacle avoidance mode. In this mode, the light control chip 30 controls an indicator light 60 to light up a specific color (for example, green), and the light control chip 30 also controls other indicator lights 60 to light up other colors. When playing the game, the player needs to manipulate the direction control component 50 to control the movement of the light of a specific color to avoid the light of the specific color being in the same position as the lights of other colors. When the main control chip 20 detects that the direction control key of the direction control component 50 is pressed, it notifies the light control chip 30 to control the extinguishing of the indicator light 60 at the current position and controls the indicator lights 60 in the adjacent corresponding directions to light up the lights of a specific color, presenting a light moving effect. The game is determined to have failed until the main control chip 20 detects that the light moving position is the same as the light position of other colors.

[0040] The third game mode may be a pursuit mode, in which the light control chip 30 controls the first indicator light 60 at a random position to light up the light of the first color (e.g., white), the second indicator light 60 to light up the light of the second color (e.g., green), and the third indicator light 60 to light up the light of the third color (e.g., red). During the game, the player needs to manipulate the direction control member 50 to control the movement of the light of the first color to avoid the light of the first color and the light of the third color being in the same position. During the process of the light control chip 30 continuously controlling the indicator light 60 to light up multiple times, the indicator light 60 may be controlled to switch the light of the second color to the light of the first color, and at the same time, multiple indicator lights 60 on a specific route may be controlled to light up the third color in sequence, presenting a light movement effect. When the main control chip 20 detects that the direction control key of the direction control member 50 is pressed, it notifies the light control chip 30 to control the light of the indicator light 60 at the current position to turn off and control the indicator lights 60 in the adjacent corresponding directions to light up the light of the first color, presenting a light movement effect. Until the main control chip 20 detects that the moving position of the light of the first color is the same as the light position of the third color, the game is determined to have failed.

[0041] The fourth game mode may be a color matching mode. In this mode, when the main control chip 20 detects that a button 40 at a certain position is pressed or touched, it notifies the light control chip 30 to light up a certain color of light at the corresponding position. Players need to press or touch the corresponding button 40 to light up the paired lights of the same color during the game. The light control chip 30 controls the indicator lights 60 at the same position to keep lighting up the same color of light. When the main control chip 20 detects that two buttons 40 pressed or touched continuously light up paired lights of the same color, it notifies the light control chip 30 to keep the indicator lights 60 always on. When the main control chip 20 detects that two buttons 40 pressed or touched continuously light up lights of different colors, it notifies the light control chip 30 to turn off the indicator lights 60 at the corresponding position. The game is determined to be over when the main control chip 20 detects that all indicator lights 60 are always on.

[0042] The fifth game mode may be a memory chain mode, in which the light control chip 30 lights up different colors in different areas, and then controls the indicator lights 60 in different color areas to flash in a specific order. When playing the game, the player needs to press or touch the corresponding buttons 40 in the same color flashing order. When the main control chip 20 detects that the pressing order of the buttons 40 is the same as the flashing order of the indicator lights 60, the game is determined to continue, otherwise the game is determined to fail.

[0043] The sixth game mode may be a time-limited competition mode, in which the light control chip 30 controls multiple indicator lights 60 at random positions to light up with the same color, and the player needs to turn off the lights by pressing or touching the corresponding buttons 40 during the game. The main control chip 20 determines that the game is successful when it detects that the corresponding buttons 40 are all pressed or touched within the limited time, otherwise it is determined that the game fails.

[0044] The seventh game mode may be a minesweeper mode, in which the light control chip 30 controls all indicator lights 60 to light up a certain color (such as green), and the player needs to press or touch the corresponding button 40 to turn off the corresponding indicator light 60 or change the light color of the corresponding indicator light 60. When the main control chip 20 detects that the button 40 is pressed or touched to turn off the corresponding indicator light 60, the game is determined to continue, and when the main control chip 20 detects that the button 40 is pressed or touched to change the light color of the corresponding indicator light 60, the game is determined to fail.

[0045] In this embodiment, the switch unit 500 includes a main switch 71, an audio switch 72 and a mode switch 73, wherein the main switch 71 is used to turn on or off the power supply, the audio switch 72 is used to adjust the volume of the audio playback device 400, and the mode switch 73 is used to switch the game mode. The connection method of the switch unit 500 is specifically that one end of the main switch 71 is connected to the switch control terminal 25 and is connected to the power output terminal 22 through the fifth resistor (R5), the other end of the main switch 71 is grounded, the audio switch 72 is connected in parallel with the main switch 71 through the sixth resistor (R6), and the mode switch 73 is connected in parallel with the main switch 71 through the seventh resistor (R7). Obviously, in other embodiments of the utility model, if the audio playback device 400 is not provided on the main control chip 20, the switch unit 500 may not be provided with an audio switch 72.

[0046] For clarity, certain features of the utility model described in separate embodiments may be combined in a single embodiment. Moreover, various features of the utility model described in a single embodiment may also be used in a sub-combination alone or in any suitable form.
