📌 Code Examples & Usage – TM1637 0.56″ 4-Digit LED Time / Clock Display

📋 Overview

The TM1637 4-digit LED display module is a compact, easy-to-use display commonly used for:

  • Digital clocks & timers

  • Counters

  • Temperature displays

  • Voltmeters / panel meters

  • Status indicators

It requires only two signal wires (CLK and DIO), making it ideal for Arduino, ESP32, ESP8266, and Raspberry Pi projects.

Available in multiple LED colours:
Red / Blue / Green / Yellow / White

🔌 Wiring (Very Simple)

TM1637 Pin Arduino ESP32 (Example)
VCC 5V 3.3V
GND GND GND
CLK D2 GPIO16
DIO D3 GPIO17

✔ Logic works at 3.3V or 5V
✔ No level shifting required

📦 Library Installation (Arduino IDE)

  1. Open Arduino IDE

  2. Go to Sketch → Include Library → Manage Libraries

  3. Search for TM1637

  4. Install TM1637Display by Avishorp (recommended)

🧪 1️⃣ Arduino Example – Display a Number

#include <TM1637Display.h>

#define CLK 2
#define DIO 3

TM1637Display display(CLK, DIO);

void setup() {
display.setBrightness(0x0f); // 0x00–0x0f
}

void loop() {
display.showNumberDec(1234); // shows 1234
delay(2000);

display.showNumberDec(56, true); // shows 0056
delay(2000);
}

⏰ 2️⃣ Arduino Example – Digital Clock (HH:MM with Colon)

The colon is controlled using showNumberDecEx().

#include <TM1637Display.h>

#define CLK 2
#define DIO 3

TM1637Display display(CLK, DIO);

int hours = 12;
int minutes = 0;
bool colon = true;

void setup() {
display.setBrightness(0x0f);
}

void loop() {
int timeValue = hours * 100 + minutes;

// 0x40 turns the colon ON
display.showNumberDecEx(timeValue, colon ? 0x40 : 0x00, true);

colon = !colon; // blink colon
delay(500);

minutes++;
if (minutes >= 60) {
minutes = 0;
hours++;
if (hours >= 24) hours = 0;
}
}

✔ Works as a basic clock
✔ Colon blinks every 0.5s

🧪 3️⃣ ESP32 Example – Counter Display

#include <TM1637Display.h>

#define CLK 16
#define DIO 17

TM1637Display display(CLK, DIO);

int count = 0;

void setup() {
display.setBrightness(0x0f);
}

void loop() {
display.showNumberDec(count, true);
count++;
if (count > 9999) count = 0;
delay(500);
}

🎚 4️⃣ Brightness Control

Brightness range: 0x00 (dim) → 0x0F (bright)

for (int b = 0; b <= 0x0f; b++) {
display.setBrightness(b);
display.showNumberDec(b);
delay(300);
}

🧠 Common Use Cases

  • Real-time clock display (with RTC module like DS3231)

  • Temperature display (with DS18B20 / DHT sensors)

  • Countdown timers

  • Speed / RPM counters

  • Voltmeter readouts

🧠 Tips & Troubleshooting

✔ If the display shows nothing:

  • Check CLK/DIO wiring

  • Check brightness (not set to 0)

✔ If numbers are reversed:

  • Rotate the module or adjust mounting orientation

✔ Colon not lighting:

  • Ensure you are using showNumberDecEx() with 0x40

✔ Leading zeros:

display.showNumberDec(value, true);
