7 Segment Display 4 bit Common Anode LED Module TM1637

The TM1637 Display Module is a 4-digit 7-segment LED display that is easily controlled using just two signal wires from a microcontroller, such as an Arduino. It integrates the TM1637 controller chip, which handles all aspects of segment control, digit multiplexing, and brightness adjustment. This allows the microcontroller to offload display tasks and focus on more important processing functions.

Pinout:

Pin Name Description
1 CLK Clock signal input
2 DIO Data I/O
3 VCC Power supply (3.3V–5V)
4 GND Ground

Arduino Library:

Wiring with Arduino:

  • CLK → Arduino Digital Pin 2
  • DIO → Arduino Digital Pin 3
  • VCC → 5V
  • GND → GND

Example Arduino Code:


#include "Arduino.h"
#include "TM1637Display.h"

#define CLK 2
#define DIO 3
#define TEST_DELAY 2000

const uint8_t SEG_DONE[] = {
  SEG_B | SEG_C | SEG_D | SEG_E | SEG_G, // d
  SEG_A | SEG_B | SEG_C | SEG_D | SEG_E | SEG_F, // O
  SEG_C | SEG_E | SEG_G, // n
  SEG_A | SEG_D | SEG_E | SEG_F | SEG_G  // E
};

TM1637Display display(CLK, DIO);

void setup() { }

void loop() {
  uint8_t data[] = { 0xff, 0xff, 0xff, 0xff };
  display.setBrightness(0x0f);
  
  display.setSegments(data); // All segments ON
  delay(TEST_DELAY);

  data[0] = display.encodeDigit(0);
  data[1] = display.encodeDigit(1);
  data[2] = display.encodeDigit(2);
  data[3] = display.encodeDigit(3);
  display.setSegments(data);
  delay(TEST_DELAY);

  display.clear();
  display.showNumberDec(301, false); // Show number without leading zeros
  delay(TEST_DELAY);

  display.showNumberDec(-999); // Show negative numbers
  delay(TEST_DELAY);

  display.clear();
  display.showNumberHexEx(0xf1af); // Show hex
  delay(TEST_DELAY);

  // Brightness test
  for (int i = 0; i < 7; i++) {
    display.setBrightness(i);
    display.setSegments(data);
    delay(TEST_DELAY);
  }

  // Final message
  display.setSegments(SEG_DONE); // Show "done"
  while(1);
