It closes.
After microcontroller U1 is powered, microcontroller U1 is initialized first, including is initialized to I/O port：By the end P1.0, P1.1
Mouth is set to input state, is convenient for reading the state of combination button switch in this way.The port P3.7, P3.5 is set to output state, so
Sound-producing device S1 is set to mute state afterwards, i.e.,：The ports P3.5 export low level, and light-emitting device L1 is set to extinguishing shape
State, i.e.,：The ports P3.7 export high level.
Then microcontroller U1 starts to read P1.0, P1.1 mouthfuls of level state, if the port P1.0, P1.1 is high electricity
It is flat, then it is assumed that conductive sheet A1, B2 are not pressed in combination button switch J1, at this time that control sound-producing device S1 is mute, shine
Device L1 extinguishes, i.e.,：The ports P3.5 export low level, P3.7 mouthfuls of output low levels.It then proceedes to read the port P1.0, P1.1
Level state.If it is this condition of high level to be unsatisfactory for the port P1.0, P1.1, continue to determine whether to meet the ports P1.0
It is this condition of high level for low level, the ports P1.1.
If the ports P1.0 are low level, the ports P1.1 are high level, then it is assumed that conductive sheet A1 quilts in combination button switch
It presses and contacts but do not contacted with conductive sheet C3 with conductive sheet B2, conductive sheet B2 receives low level, and conductive sheet C3 is not received
To low level.I.e.：Conductive sheet B2 is low level, and conductive sheet C3 is high level.Then light-emitting device L1, sound-producing device S1 press Fig. 7 moulds
Formula works, i.e.,：P3.5, P3.7 mouthfuls of equal output timings are square-wave signal shown in Fig. 7, then proceed to read the end P1.0, P1.1
The level state of mouth.If be unsatisfactory for, the ports P1.0 are low level, the ports P1.1 are this condition of high level, and continuing judgement is
It is no that meet P1.0, P1.1 mouthfuls be this condition of low level.
If the port P1.0, P1.1 is low level, then it is assumed that conductive sheet A1 is led by by earth in combination button switch
Electric piece A1, B2, C3 are touched together, i.e.,：Conductive sheet B2, C3 receive low level.Therefore conductive sheet B2, C3 are low electricity
It is flat.Then control sound-producing device, sound-producing device by the work of Fig. 8 patterns, i.e.,：The equal output timing in the port P3.5, P3.7 is shown in Fig. 8
Square-wave signal then proceedes to the level state for reading the port P1.0, P1.1.If it is low to be unsatisfactory for the port P1.0, P1.1
This condition of level then continues to read P1.0, P1.1 mouthfuls of level state.So far entire cycle criterion executes operation completion, single
Piece machine U1 will constantly execute the above cycle criterion operation.
Therefore:When the button 6 in combination button switch J1 is not pressed, conductive sheet B2 and conductive sheet C3 are by resistance
R1, R2 are pulled to high level, and light-emitting device L1 and sound-producing device S1 does not work at this time；When the button for pressing combination button switch J1
6, when conductive sheet A1 being made to be pressed and contact but do not contacted with conductive sheet C3 with conductive sheet B2, conductive sheet B2 current potentials become low electricity
It is flat, and conductive sheet B2 and conductive sheet C3 not in contact with, so conductive sheet C3 is still high level at this time, microcontroller U1 read P1.0,
The level state of the ports P1.1, the ports P1.0 are low level at this time, the ports P1.1 are high level, microcontroller U1 P3.5,
The slow square-wave signal of the equal output timing in the ports P3.7, at this time sound-producing device S1 send out the slow sound of rhythm, simultaneously shine
Device L1 flickers are gentle；When pressing the button 6 of combination button switch J1, conductive sheet A1 be pressed and with conductive sheet B2, C3
It contacts, the current potential of conductive sheet B2, C3 all becomes low level at this time, and microcontroller U1 reads the level of the port P1.0, P1.1
State, the port P1.0, P1.1 are low level, in the rectangular wave that the equal output timing in the port P3.5, P3.7 of microcontroller U1 is rapid
Signal, sound-producing device S1 sends out the rapid sound of rhythm at this time, while light-emitting device L1 flickers are frequent.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
The scope of protection of the utility model is also should be regarded as into deformation.
