4-Digit 7-Segment Display

Description

4-Digit Display module is a 12-pin module. In this module, we use a TM1637 to scale down the number of controlling pins to 2. That is to say, it controls both the content and the luminance via only 2 digital pins of Arduino or other mcu board. For projects that require alpha-numeric display, this can be a good choice.

Features

• 4 digit red alpha-numeric display
• Arduino compatible interface (3.3V/5V)
• 8 adjustable luminance levels

Specifications

Application Ideas

• Time display
• Stopwatch
• Sensors’ input display

Hardware Connection

The display module has 4 pins:

• VCC & 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
