Arduino platform-based colorful flash stick system

Abstract

The invention discloses an Arduino platform-based colorful flash stick system, which comprises a boosting circuit, an ATTiny85 control circuit, a full-color LED and a USB interface, wherein the ATTiny85 is connected with the boosting circuit, an LED light strip, the USB interface and other accessories respectively. The Arduino platform-based colorful flash stick system has the beneficial effects that the eight-pin ATTiny85 is adopted as main control, the first pin is a software burn-write reset end, the second pin is connected with the second data end of the 10 USB interface, the third pin isconnected with the third data end of the USB interface, the fourth pin is grounded, the fifth pin is connected with a 6 vibration sensor, the sixth pin is connected with the data input end of the 9 full-color LED, the seventh pin is connected with an 8 key switch, and the eighth pin is connected with the output end of the 4 boosting circuit. The pins are made full use of, the circuit is concise, and the welding and the making are easy; besides, the SK6812 full-color LED is used as a display part, and multi-color display is realized. By adopting the 1.5V-5V boosting circuit, normal operation can be carried out with one 1.5V battery, the size and the weight of the rocking stick are reduced, and the portability and the user experience are enhanced.

Description

technical field

[0001] The invention relates to an intelligent hardware, in particular to an intelligent hardware based on an Arduino platform. Background technique

[0002] At present, there are some shaking sticks on the market that can be shaken by hand to emit light and form patterns. The human eye can see a complete picture, forming patterns of different colors and shapes. Most of the main control chips of existing rocking sticks are various 51 single-chip microcomputers. The number of pins of the 51 single-chip microcomputer far exceeds the actual demand, resulting in a lot of waste of ports and greatly increasing the difficulty of welding. Most of the existing lamp beads are ordinary single-color LED lamps, and the color is single and boring, which cannot meet the needs of various occasions. At the same time, since the working voltage of the lamp beads and other devices is mostly 5V, the current solution is to supply power with three 1.5V dry batteries or batteries...

Examples

Embodiment Construction

[0014] user mode:

[0015] step one: figure 2 The middle 6 power switch is turned on, the power light is on, the dry battery provides 1.5V voltage, which is boosted by the 4 boost circuit, and the output VCC voltage value is 5V at the end of the 4 boost circuit.

[0016] Step 2: VCC of 5V starts to supply power to devices such as 2ATTiny85 chips and 1 series-connected full-color LED strip. The LED lights up, and the flash stick starts to run according to the compiled program.

[0017] Step 3: Shake the stick body, 3 vibration detection sensors sense the vibration frequency, and transmit it to 2ATTiny85 chip, the main control chip controls the colorful lamp beads according to the existing compilation and frequency, and a specific colorful pattern appears.

[0018] Step 4: Press the 5 display switching button to switch the stored patterns and repeat step 3, which is interesting and colorful.

[0019] Step 5: Turn off the 6 power switch after use.
