Description TM1637 is a chip for driving 7-segment displays. There are several modules using this chip to form a 4 digit numerical display module (sometimes called #34;Digital Tube #34;). These modules are available, for example, from DX and SeeedStudio. Key Features Use either raw segment values or decimal numbers (with and without leading zero) Set either the whole display or any digit independently Control the brightness Pure software implementation Note: the TM1637 has also keyboard input capability, which is not implemented in this library. Hardware Connection The display module has 4 pins: VCC amp; GND - Self explanatory CLK - Clock; connect to any digital pin on the Arduino DIO - Data I/O; connect to any digital pin on the Arduino When a TM1637Display object is created, the clock and data pin numbers are passed as arguments and get bound.
