Displaying Time, Date, Temperature and Humidity on a LCD2004 Display

We were already playing around with a LCD2004 display in a previous tutorial where we displayed the temperature and the humidity <===> First Steps with the Arduino-UNO R3 and NANO | Maker, MakerED, Coding | I2C LCD Temp./Humidity displaying, now we will add as well Time and Date with a DS3231 module.

We will use the tutorial from <===> Arduino datalogger with SD card, DS3231 and DHT22 sensor, where we will NOT use the datalogger for our project to make it as easy as possible; courageous ones, once the project is working for them, may add the datalogger 😉 In that tutorial you will find also the code…

Please check video tutorial below:

Check also the blog below, please:

.

Check the schematic above please to know how to wire it; first we will do it on a breadboard and later we could solder it… Do the wiring as shown, without the Datalogger-SDCard-Module. See PIC below, please.

In the above image you will see an DHT11 Sensor (blue case) as at the time I didn’t have it yet (was ordered…) a DHT22 Sensor (white case) as shown on the finished project. As the project works we can now solder everything together on a strip-board, choosing a case; I used a cardboard box with the dimensions of 140 mm X 130 mm X 60 mmm, fixing the LCD2004 and the DHT22-Sensor on the front of the cardboard box.

As you can see in above image, I added some text with a Dymo tape, looks better 😉

The Sketch (Code) for the project

One thing missing, the sketch (code). Please find it below and open it , copy it and paste it to the Arduino IDE:

• LCD2004-DHT22-DS3231-Sketch

Read the comments in the sketch to understand the changes which I made to the original, it’s actual easy…
