While it is possible to write raw C++ code to bit-bang the TM1637 protocol, it is inefficient for learning. The Arduino community has created excellent libraries to abstract the complexities. We will use the most standard library: .
void setup() // Initialize the display display.setBrightness(0x0f); // Set brightness to maximum (0x00 is min, 0x0f is max)
delay(1000); // Wait 1 second
