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.

A very easy Genuino UNO project with LCD and DHT11 temp. and humidity sensor. The LCD shows the temp., humidity and other infos.

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.

A very useful project, made to monitor system resources without opening Task Manager.

A digital clock using minimum components.
