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...

Most of the existing lamp beads are ordinary single-color LED lights, and the color is single and boring, which cannot meet the needs of various occasions

At the same time, since the working voltage of lamp beads and other devices is mostly 5V, the current solution is to supply power with three 1.5V dry batteries or batteries, which greatly increases the weight and volume of the rod, and reduces the portability and user experience.
