You can create and control multiple display objects with different names and connection pins. These displays are fantastic for displaying sensor data, temperature, time, etc. In the first example, we will look at the basic functions of the TM1637Display library. In the second example, I will show you how you can display the time on a 4-digit display. The last example can be used to create a simple temperature display in combination with the DHT11. After the example, I break down and explain how the code works, so you should have no problems modifying it to suit your needs. ![]() ![]() Two pins are required for the power connections and the other two pins are used to control the segments. The segments are labeled A to G and some displays also have a dot (the 8th LED). Use this image as a reference when setting the individual segments in the code later. The color, size, dots, and connection points can all be different. I dont have experience with all the different versions of this display but as long as they use the TM1637, the code examples provided below should work. For more information, you can check out the datasheet below. You only need to connect 4 wires: 2 for power and 2 to transfer the data. You just have to change the pin configuration in the code accordingly. This library has several built-in functions that make controlling the display fairly easy. I will explain how each function can be used in more detail below. Next, go to Sketch Include Library Add.ZIP Library in the Arduino IDE. 11 Segment Display Update The ListThe Library Manager will open and update the list of installed libraries. Make sure that you have the correct library installed, otherwise you will get an error message while compiling the code. The statement define is used to give a name to a constant value. The compiler will replace any references to this constant with the defined value when the program is compiled. So everywhere you mention CLK, the compiler will replace it with the value 2 when the program is compiled. Note that I called the display display, but you can use other names as well like temperaturedisplay.
