Abstract

The utility model discloses a double-color LED shaking stick, which comprises a single-chip microcomputer module. The single-chip microcomputer module is respectively connected with an LED display module, a download port module, a power supply module, a mercury switch and a key switch. The double-color LED shaking stick is controlled by the single-chip microcomputer. When the double-color LED shaking stick is shaked by hands, a visual plane is generated at the shaking region of the double-color LED shaking stick due to the visual persistence effect. Through the refreshing variation of different frequencies, a light-emitting diode in the visual plane generates images within the shaking region. Therefore, the double-color LED shaking stick can display different patterns or characters through the compiling of different character codes.

Description

The dual-colored LED swing stick

Technical field

The utility model belongs to the electronic entertainment product technical field, relates to a kind of dual-colored LED swing stick.

Background technology

In the occasion of many indoor and outdoor matches, performance, party, swing stick often is used for enlivening on-the-spot atmosphere by people, transfers spectators' enthusiasm.Can only send single light yet existing swing stick is many, function ratio is more single.

Summary of the invention

The purpose of the utility model provides a kind of dual-colored LED swing stick, can carry out diversified writings and image and show.

The technical scheme that the utility model adopted is, a kind of dual-colored LED swing stick comprises one-chip computer module, one-chip computer module respectively with the LED display module, download a mouthful module, supply module, mercury cut-off, keyswitch and be connected.

The characteristics of the utility model also are,

One-chip computer module adopts the STC89C52 single-chip microcomputer.

Supply module is made up of two CR2032 batteries.

The LED display module is made up of 16 high bright LED light emitting diodes of redness and 16 high bright LED light emitting diodes of green.

The beneficial effect of the utility model is, through Single-chip Controlling, when manually rocking the dual-colored LED swing stick; Because visual persistence effect; Can produce a visual plane in the zone of shaking of dual-colored LED swing stick, the light emitting diode in visual plane can produce image through the variation that refreshes of different frequency in shaking the zone; Through writing the different literals coding, can make the dual-colored LED swing stick show different pattern or literal.

Description of drawings

Fig. 1 is the structural representation of the utility model dual-colored LED swing stick.

Among the figure, the 1.LED display module, 2. one-chip computer module is 3. downloaded mouthful module, 4. supply module, 5. mercury cut-off, 6. a keyswitch.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.

The structure of the utility model dual-colored LED swing stick, as shown in the figure, comprise one-chip computer module 2, one-chip computer module 2 is connected with LED display module 1, a download mouthful module 3, supply module 4, mercury cut-off 5, keyswitch 6 respectively.

Wherein one-chip computer module 2 adopts the AT89S52 single-chip microcomputer.

Wherein supply module 4 is made up of two CR2032 batteries.

Wherein LED display module 1 is made up of 16 high bright LED light emitting diodes of redness and 16 high bright LED light emitting diodes of green.

The principle of work of the utility model dual-colored LED swing stick does; Supply module 4 provides driving for the dual-colored LED swing stick, is connected with PC through downloading a mouthful module 3, can program code be downloaded in the one-chip computer module 2; The control that one-chip computer module 2 is realized output signal frequency; Mercury cut-off 5 is used for the current state position of shaking of perception dual-colored LED swing stick, and LED display module 1 can realize that the light on and off of different frequency refresh, and keyswitch 6 can be used for to the conversion of displaying contents.Write the character code that will show and download in the one-chip computer module 2 of dual-colored LED swing stick; When manually rocking the dual-colored LED swing stick; Because visual persistence effect; Can produce a visual plane in the zone of shaking of dual-colored LED swing stick, the light emitting diode in the LED display module 1 in visual plane can produce image through the variation that refreshes of different frequency in shaking the zone.

Through downloading a mouthful module 3 program code in the PC is downloaded in the one-chip computer module 2; One-chip computer module 2 adopts the AT89S52 single-chip microcomputer; LED display module 1 is made up of 16 high bright LED light emitting diodes of redness and 16 high bright LED light emitting diodes of green, and the P0 mouth ~ P2 mouth of STC89C52 single-chip microcomputer is connected with 16 high bright LED light emitting diodes of redness and 16 high bright LED light emitting diodes of green by being total to the anode mode, and the contact of mercury cut-off 5 the right and lefts is connected with two external interrupt P3.2, P3.3 of AT89S52 single-chip microcomputer respectively; Be defaulted as high level; Mercury cut-off rocking bar ground connection, mercury cut-off are in different positions and then get into different interruptions, thereby have determined the LED swing stick in the different content of different position display; Supply module 4 is made up of two CR2032 batteries; Be connected with the VCC pin with the GND pin of STC89C52 single-chip microcomputer, keyswitch 6 is connected with the P3.0 of AT89S52 single-chip microcomputer, is used for carrying out picture and switches.
