Spring Festival "Fireworks" (exploding capacitor) based on attiny85

Overview

Due to cost issues, I only designed 8*8*2. In theory, it can be stacked longer. As long as the DOUT of the upper level MAX7219 is connected to the DIN of the next level, it can be used (CS/CLK are all connected together). In order to be lazy in wiring, I didn't connect them in order. (It's a fried capacitor, not a dot matrix screen anyway, so it doesn't matter.) Leave the pins of attiny85 and plug them in directly. And leave other pins of attiny85 to expand the 443M wireless remote control module for remote ignition. See the attachment for the program. The logic written casually using mixly can actually be more rigorous.
ATTINY85 drives Baidu by itself.
