The bicycle hot wheels dynamic pattern is made by the program written by the single chip microcomputer to control the time when the led lights are turned on and off. Similar to the principle of hand-drawn animation.
First draw the various patterns with dedicated software, then store the edited pattern files on the hot wheels. After turning on the switch, the MCU in the hot wheels will control the opening and closing time of the led lights according to the pattern on the file. After the wheels are turned, the pattern will appear on the wheels.
