A 4-digit 7-segment LED display has 12 pins. 8 of the pins are for the 8 LEDs on each of the 7 segment displays, which includes A-G and DP (decimal point). The other 4 pins represent each of the 4 digits from D1-D4. The pinout for the LED segment is shown below. The
A 7 segment LED display consists of 7 LEDs arranged in such a way that it can display nuers from 0 to 9. The arrangement of LEDs in the display can be either common anode or common hode. In this project, a 4 – digit 7 – segment LED display is used to display nuers using Arduino.
Adafruit Industries, Unique & fun DIY electronics and kits Adafruit 0.56 4-Digit 7-Segment Display w/I2C Backpack - Yellow : ID 879 - What''s better than a single LED? Lots of LEDs! A fun way to make a small display is to use an 8x8 matrix or a 4-digit 7-segment display. Matrices like these are ''multiplexed'' - so to control all the seven-segment LEDs you need 14 pins.
The PCB has the same dimensions as the RobotDyn 4-Digit LED Display Tube, 7-segments, TM1637, 50x19mm module. The genuine part can be found on various maker sites on the Internet including eBay. They’re targetted at Arduinio users and of course there are lots of clone versions around too.
Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-hode module containing four 7-segment LED numeric displays. Each segment in the display module is multiplexed, meaning it shares the same anode connection points.
Writing in a 4 digit 7 segment LED display. And found it interesting, I fixed the code and made a Fritzing example for all you interested, Good luck!

Serial 7-segment LED display module (4 digits) This serial LED display module allows you to interface a 4-digit 7-segment LED display with only three I/O pins of a microcontroller, and gives you full control of all digits and decimal points. 4-digit serial seven segment LED display.
This 4-digit 7 segment display module has two colors to choose: red and green. It supports 8-level brigthness adjustment and can be drived via two normal I/O ports. Standard IIC pins, compatible with Gravity interface, free from MCU scanning. Specifiion. Power Supply: DC 5V; Two Display Modes: 8 segment × 4-digit and 7 segment × 4-digit
21/5/2017· The NodeMCU serial port will show the IP address and the connection satatus,then print the command from MQTT client.NOTE: When the nuer is between 0 and 191, it can be displayed normally.The initial state output value is 83. Open the MQTTBox and publish different nuer(0~191) to the broker, The 4 digital LED display will show as below :
The module consists of four 7- segment displays working together. The module working is based on ‘TM1637’ IC present internally and hence the name ‘TM1637 display’. TM1637- Grove 4 Digit Display Module Datasheet, Pinout, Features and Working

The seven segment Module is multiplexed module of 4 pcs 7 segment display and TM1637 driver IC. the module makes easy to interface with Arduino, controller or process as it is already multiplexed. For makes, it is difficult to multiplex all the 7 segments LED display to make a clock or display 4 digit …
How to Interface 7-Segment displays with Pic Microcontroller; ADC Value on 7 Segment Circuit Diagram. In this project, we used a common hode type 4-digit 7 segment display with a PIC16F877a microcontroller. This circuit shows a connection diagram of the 4-digital 7-segment display, a variable resistor, and PIC16F877A.
This project is a 7 segment LED display module that can be driven using SPI protocol, so it needs only 3 pins of your mcu to drive 4 x LED displays. It’s based on MAX7219 LED display driver. Description Seven segment LED displays are very popular for displaying numeric information because they are very attractiveRead More
Using 4 digit 7 segment LED. 6. 7-segment LED display with multiple digits. 0. 4 digit 7 segment CC - all digits count the same nuer. 1. Driving two large 7-segment displays using Arduino and shift registers. 0. How to display a double digit decimal value on a seven segment display? 0.
