Just part of a big project while I'm doing testing on DS3231 RTC module with LCD keypad shield. I think this can be shared.

Arduino Nano 32x8 LED matrix displaying date, time, temperature and humidity with a motion sensor.

This is how to make your own LCD timer, just with an Arduino, a LCD screen and some hook-up wires.

It shows the current temperature on an 8*8 dot matrix display using DHT11 temperature sensor.

Control the LCD contrast and background LED with analogWrite!

Cool project to begin with 128x64 OLED, done with a twisted logic to fix the refresh flashing screen.

A 16x16 LED display matrix that can display any 16x16 pixel image.

A word clock using an OLED display.

Wire a 16x2 LCD.

How to drive old binary input HEX LED display with Arduino.

With this system, guess the number in between any range required according to the situation.

Use Arduino MKR1000 and a LCD to set the message of the day.

In this project, I am going to demonstrate to you how to show time with 12 LEDs on the idIoTware shield.

An alarm clock with no physical buttons, just a remote control.

8x8 RGB LED matrix x 8 = 16x32 RGB LED matrix.
