ESP8266 WiFi Weather Station with Color TFT Display

We were playing around already with LED MATRIX’s, devices to visualize measured values and/or texts. In this blog post (Tutorial) we will use a TFT Display (Thin-film-transistor liquid-crystal display) with touch screen to display a three (3) days weather forecast with moon phases. This little weather station acquires its data over a Wi-Fi connection from an online weather server, Wunderground.

We will use devices from ADAFRUIT; they have developed a special product series for easy mounting, the FEATHER series. We need the TFT FeatherWing – 2.4″ 320×240 Touchscreen and the ADAFRUIT Feather HUZZAH which has included an ESP8266. We used the ESP8266 already in our previous blog post <===> First Steps with the ESP8266 Wi-Fi Module | Maker, MakerED, Coding | Scrolling Text (Time, Temp., Humidity…) with 8×8 LED MATRIX  <===> so we are already familiar with its use!

What is GREAT with this project, there ISN’T any wiring, no cables to connect; apart from plugging in the accumulator! 😉 BUT, please check the video below who explains in detail:

I suggest to you to read the full article from ADAFRUIT here <===> https://learn.adafruit.com/wifi-weather-station-with-tft-display/overview?embeds=allow  <===> who explains in detail ALL the necessary steps!!

For the case of the weather station ADAFRUIT provides the 3D Design files, so you can 3D print it:

As you can see the price is reasonable for this project, ONLY 62.40$ and easy to realize! ALL what YOU need is a bit time, passion and here we GO! 😉 Have FUN!

Preparation: Libraries, code and API Key

There is some preparation needed before we can test our code for the weather station: I suggest that you read and that you follow each step as shown in this tutorial by ADAFRUIT (very important, otherwise it won’t work!!):

It isn’t difficult, but it needs some time and you must be careful to follow each step!

We need ALSO an account on the weather server Wunderground to create our “API” (Application Programming Interface) which we need to implement in our code settings! THIS is also well explained here:

Same procedure as explained already above, follow very carefully each action step by step!

.

Are there some pit falls? 

1ibdy1vf6wghd-n05dgl-attenzionearchitettofr01YES, this could be!

.


The code is running, how it shows up in reality

Well, you haven’t encounter any problem or the problems are solved, this is WHAT you will see appearing on the TFT:

1
Updating Time
2Updating Conditions
3Updating Forecasts 4Updating Astronomy
5Done...  6Wrong settings code

.

As you can see in “Picture 6“, that is what shows up on the first start! Is it the right time which is displayed? Is it the right measure unit which is displayed (°C OR °F)? If SO, it is OK then, if NOT, then we have to look on the code and change some settings!!

Here below the How-To:

Open the Arduino IDE and click on the “Settings.h” tab, check below where and how to change (adapt) the settings to your country and time zone.

Once done, save the code and upload it again. You will GET the right data displayed then as shown below:

First Steps with the ESP8266 Wi-Fi Module | Scrolling Text (Time, Temp., Humidity…) with 8×8 LED MATRIX 

In our previous blog post (Tutorial…), we were playing around with a LED MATRIX <===> First Steps with the Arduino-UNO R3 | Maker, MakerED, Coding | Scrolling Text with 8×8 LED MATRIX  <===> and we will continue to use the LED MATRIX, but this time with a Wi-Fi connection. We will use the module “ESP8266” which you can purchase worldwide around as it is very popular and it costs ONLY 7.49 €. I ordered mine on Amazon in Germany:

Good to know is the PINOUT of the ESP8266

Before we can use the module “ESP8266” and before the wiring we need to do some preparation:

.

Check the video below please who explains the first steps with the ESP8266:

.

.

Now that we have configured the ESP8266 in the Arduino IDE we need some other information which are necessary to implement into the code. It is the name of the Wi-Fi Network (SSID) and the Password for the Wi-Fi Network.  AND a new device connecting to the router (the ESP8266) must GET allowed to do so, if your router is well configured for Cyber-Security! Thus meaning for Cyber-Security reasons: in the router security settings any device connecting to your Wi-Fi Network SHOULD NOT have access unless it is your own ones and unless you allow THEM to access!

.

My shown images from the Router are from a “FritzBox Router“, but it should be similar in other Routers!!

.

Click image, please, to enlarge.

In the above image you see which devices are connected to your Network, to do so: open your router with your login and/or password and look under “Radio Network” (or similar). IF you don’t see your “ESP8266” in the Network while you run the code and it isn’t working does mean that your Network is well secured as it doesn’t allow any other device connecting to the Network!

Router-2-corr

Click above image, please, to enlarge.

.

You need then to give permission to the device to connect. To do so: Open the Security settings in your Router and click on “Allow all new wireless devices“. NOW, you will see that the “ESP8266” is part of the Network! Note down on a piece of paper its “MAC Address” and protect your Network again by clicking on “Do not allow new wireless devices“!!

.

Router-3

Click on the image, please, to enlarge.

.

NOW, click on the button “Add Wireless Device” as shown in above image.

.

Router-4

Click image, please, to enlarge.

.

A new window opens where you can add the new devices “MAC Address” which you wrote down before. Do so please and then click the button “OK“. Go back and have a look if the device is now in the authorized devices in your Network.

Required:

  • SSID
  • WLAN Password
  • Acces authorization for the Wi-Fi

The Code for the ESP8266 and first try

I used a video tutorial in German from Switzerland as well as its Code for this project as it is very well explained. Even if you don’t understand German, you can follow step by step in the video:

.

.

While watching the video on YouTube, you will find the download link for the code, check below please:

.

Video Tutorial-2

Click image, please, to enlarge.

.

You can find another interesting code here on the blog as well as the wiring diagram and a GREAT description (in German):

Unzip the code and install it by following the video instructions; check @ 8.30 minutes and follow step by step…

After everything is installed and the code is in the Arduino IDE you need to adapt the code to your needs: check video @ 10.36 minutes

  • Entering your Network name, the SSID
  • Entering the Network-Key; Check above Router images…

.

1ibdy1vf6wghd-n05dgl-attenzionearchitettofr01When you run the code for the first time: disconnect the two wires for the power supply (GND and VCC) as the LED Matrix will light all the dots and the power consumption will be by 1.5 Ampere; thus meaning the components, especially the chips will become hot, even could get overheated!! Once the Arduino IDE shows you that the code is uploaded reconnect them and it should work.

.

That’s it folks; now you can run the code and have fun! I takes a bit time before the code runs: first “Compiling Sketch…“, followed by “Uploading…” and “Done Uploading…” and the ESP8266 tries to connect with the Wi-Fi Network…

Connecting

.

If everything was made correctly as described above you should receive now your personal weather data… FIRST the time will GET displayed for a couple of seconds (that period could GET changed by your settings in the code…)…

.

Time

.

Then the scrolling text starts displaying the temperature, humidity, air pressure, rain risk in % and wind speed…

.

Scrolling text: temp., humidity...

.

Stay tuned for next blog posts and enjoy it 😉

Have FUN with your “LEARNing-By-Doing project” and try out ALSO the other examples 😉
