In my hand is a 4-Digit 7-Segment display module. The heart of this module is an inexpensive Serial LED Driver from Titan Micro Electronics called the TM1637. In this tutorial, I am going to show you guys how to control the TM1637 4-Digit 7-Segment displays using an Arduino. If you want to displays sensor data, temperature and humidity, or want to design a clock, timer or counter, you will need this 4-Digit Seven-Segment Display. In this tutorial we are going to talk about:
- The Basics of a 7-Segment Display
- Hardware Overview and Pinout of The TM1637 Module
- TM1637 Library Installation
- Interfacing TM1637 Module with an Arduino
- Loading The Basic Arduino Code (that comes with the TM1637 library)
Then we will have a look at some of these quick examples:
- Example 1: Displaying String and a Number
- Example 2: Displaying Scrolling and Blinking Text
- Example 3: Creating a 4 Digit Counter
- Example 4: Displaying Temperature & Humidity using DHT11/DHT22
- Example 5: Creating an Arduino Based Digital Clock
And finally we will have a look at some common errors.
