This class (tm1637.js) is designed to use the TM1637 led display driver with node js. Because wiringPi is no longer available, I have decided to define a new class using pigpio to drive the TM1637 led display controller.

So, before using this class, it is necessary to install pigpio. https://npm.io/package/pigpio

You have several examples to use this class :

• display a decimal number
• display hex number
• display and scroll text (some letters are not available)

Example: the command line

sudo node decimalNumber.js

will show you some possibilities.
