SmartTM1637 is an Arduino library for controlling TM1637-based 4-digit 7-segment displays.
It supports advanced features such as decimal points, text, time display, and brightness control.

• Display numbers with optional leading zeros
• Display text and special symbols
• Display time in hour:minute format with optional colon
• Manual and automatic decimal point control
• Brightness control (0-7 levels)
• Support for uppercase, lowercase letters, numbers, and special characters
• Simple and intuitive API for easy integration

• Hardware:

  • Arduino board (Uno, Nano, Mega, or compatible)
  • TM1637 4-digit 7-segment display module
  • Connection pins (CLK and DIO) properly wired to Arduino digital pins

• Libraries:

  • No external dependencies; this library is self-contained

  delay(2000);

  display.printNumber(1234, false);  // Show number without leading zeros
  delay(2000);

  display.printTime(12, 34, true);  // Show time with colon (12:34)
  delay(2000);

  display.clear();  // Clear display
  delay(1000);
