Ive made a project using Arduino NANO, 7 segment 4 digit display Anode, 2 x 74HC959. I've got 2 identical displays, all connected to 1 Arduino NANO (in the code, you will see that its 3 display - that for the future, currently just the 2 displays are connected). The resistor values are 470 [ohm]. Here is the code I'm using.
ThisBCD-to-7 segment decoder/driver takes a four-bit BCD input labelled A, B, C and D for the digits of the binary weighting of 1, 2, 4 and 8 respectively, has seven outputs that will pass current through the appropriate segments to Howto Make 7 Segment Display Number 0 to 9 with ArduinoDownload Code: Hieveryone, I am using an Arduino Mega 2560 to control 72 high-powered LED 7 segment displays with 72 shift register (74HC595) driving transistors. The setup: 4 rows of 18 digits (consisting 3 blocks of 6 digits) every row uses 4 pins on the Arduino Mega 2560 (data, clock, latch, master reset). used pins: 22 to 37 for the 4 rows each Thestructure of the board module includes the LED driver TM1637. The driver includes the function that controls the brightness of LEDs. Connect the TM1637 4-Digit 7-Segment Display with Arduino UNO. Write the above-mentioned code and upload it to your Arduino UNO. observe the 4 digits screen. Code Explanation. Download
hello, i want to make couunter from 0 to 99 with arduino and 2 seven segment controlled by transistors . Also i have 2 push buttons one for counting up and one for counting down .I'm stuck with the code . i can write simple code for automatic counting on one 7 segmant i'm still trying but i didnt reach the write soltion yet and thx.
Inthis tutorial, we’ll see how to set up and program single digit and multi-digit seven segment displays on an Arduino. Seven segment displays come in a wide variety of sizes and colors. Red, blue,

A7 segment LED display consists of 7 LEDs arranged in such a way that it can display numbers from 0 to 9. The arrangement of LEDs in the display can be either common anode or common cathode. In this project, a 4 – digit 7 – segment LED display is used to display numbers using Arduino. Either a compact module containing four 7-
FourDigit Seven Segment Display Module. Demonstrate the Elegoo sketch provided in the tutorial covering the display module, show it shortcomings and provid
Step8: Connect to the Display. The 4511 works with common cathode (ground) displays only, but most seven segment displays are, so most of the time, you don't have to worry. A connected to: pin 13 of 4511. B connected to: pin 12 of 4511. C connected to: pin 11 of 4511. D connected to: pin 10 of 4511.
hi similar to a project that i need to do,but just starting out in the world of arduino.just need some help as its got my head done in lol.i have an arduino uno v3 and an lcd 4 digit counter.want to wire the counter to arduino and program it to show 5000.then push tactile button and it counts down quit fast to zero.then reset to 5000 and
Controling4 digit 7segment LED Display using 74HC595 shift register. I'm having troubles trying to use two 595 shift registers to output numbers on a 4 digit 7seg display. I've gotten to the point of displaying numbers correctly, but I'm now having the issue that the output is flashing some garbage between the digits being displayed.

The74HC595 chip is a shift register that allows us to reduce the number of pins, from 8 to 3 (and maybe 4), to control the 8 segments of a single 7 segment LED digit. We are going to need the 3-line SPI serial communications protocol (although we are only going to use 2) that is present in practically all microcontrollers on the market.
