Using an LCD and an LED screen

Things used in this project

Hardware components

HARDWARE LIST

1 DFRobot I2C 16x2 Arduino LCD Display Module

Link

1 Arduino UNO

1 Jumper wires (generic)

1 SparkFun 7-Segment Serial Display - Red

Software apps and online services

Arduino IDE

Story

This is a basic code which I created so that no one else will need to go through the problems of searching all the forums for the codes.

Connection

LCD= The IIC comunications port (you can modify this sine I use an unofficial UNO replacement.)

LED= GND- GND

VCC- 5V

DIO- 3

CLK- 2

I decided it would be cool since I spend 1 day looking for the library and everything to created this so that you don't have to.

Have fun and please coment on how I could improve.

Code

CODE

#include <TM1637.h>
#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 20, 4); // set the LCD address to 0x27 for a 16 chars and 2 line display



// Instantiation and pins configurations
// Pin 3 - > DIO
// Pin 2 - > CLK
TM1637 tm(2, 3);

void setup()
{
  tm.begin();
  tm.setBrightness(2);
  lcd.init();
  // Print a message to the LCD.
  lcd.backlight();
  lcd.setCursor(1, 0);
  lcd.print("The year is...");
  lcd.setCursor(2, 1);
  lcd.print("");
}

void loop()
{
  // Display Integers:
  tm.display("2021");
}
