Materials:

1. Wemos D1 Mini Pro ( Amazon / Banggood )

2. 2.8" TFT Display ( Amazon / Banggood )

3. USB Cable ( Amazon / Banggood )

4. PLA Filament ( Amazon / Banggood )

Tools Used :

1. Soldering Iron ( Amazon )

2. 3D Printer ( Amazon )

3. Wire Cutter ( Amazon )

Software:
1. Arduino IDE

First print the project enclosure

I have used my Ender3 3D printer and 1.75 mm skyblue and RED PLA filaments to print the parts.

It took me about 6 hours to print parts.

The enclosure has 3 parts:
1. case

2. Back Cover

3. Mount

My settings are:

• Print Speed: 60 mm/s
• Layer height: 0.2mm ( 0.3 also works well)
• Fill Density: 20%
• Extruder Temperature: 220degC
• Bed Temp: 60deg C

Here is the list of parts:

1. TFT display module
2. WeMos D1 mini
3. female header

insert the pin headers into the display like in the picture consider this:

if you do not need that flexibility and want to place the pin headers like in the picture then you need to solder them to the TFT Display first.

The wiring diagram is very easy. You have to connect the TFT display pins with Wemos pins as per the schematic diagram.

The schematic diagram is shown above.

TFT Display->Wemos D1

VIN -> 3.3V

GND -> GND

CS -> D1

RESET -> RST

DC -> D2

SDI -> D7

SCK - D5

LED -> D8

SDO -> D6

T_CLK -> D5

T_CS -> D3

T_DIN -> D7

T_DO -> D6

T_IRQ -> D4

With the help of soldering iron, connect all the connections to the wire as shown in the photo.

TFT Display->ESP8266

• VIN -> 3.3V
• GND -> GND
• CS -> D1
• RESET -> RST
• DC -> D2
• SDI -> D7
• SCK - D5
• LED -> D8
• SDO -> D6
• T_CLK -> D5
• T_CS -> D3
• T_DIN -> D7
• T_DO -> D6
• T_IRQ -> D4

Insert the display into the mount. Then tighten with the nut.

Apply a small amount of hot glue to secure it. Make the wiring between Header (display) and Wemos board first, then install them into the enclosure later.

Install the front Cover

After mounting the display and circuit board The enclosure is designed is not tight clearance, so you need any glue or screw to hold the front covers.

The ESP8266 module isn't part of the Arduino-IDE.

1. We have to install it first. Open file / preferences in the Aduino -IDE and insert the following link in the Additional Boards Manager URLs field: http://arduino.esp8266.com/stable/package_esp8266...

2. this window with the OK Button.

3. Open now the board manager: Tools / Board / Board Manager

4. Go to the ESP8266 board entry and install it now you can choose LOLIN(WEMOS) D1 R2 & mini.

5. Set the CPU frequency to 80MHz, Flash Size to "4MB (FS:3MB OTA:~512KB)", and the COM port.

Download all libraries
The ThingPulse Weather Station Color depends on a number of other libraries.They need to be made available to the Arduino IDE for them to be compiled and linked into the final application.

Go to Sketch > Include Library... > Manage Libraries....

Then, for each library, put its name into the text field to have its metadata pulled from the internet and displayed below. Select the latest version and install it.

Make sure to come back to this dialog from time to time to keep each library up to date. Also make sure that you only have one version of each of the libraries installed.

1. Mini Grafx by ThingPulse

2. ESP8266 Weather Station by ThingPulseJson

3. Streaming Parser by Daniel Eichhorn

4. XPT2046 Touchscreen by Paul Stoffregen

After downloading the library unzip it and installed it with your Arduino Library Manager in

Sketch > Include Library > Manage Libraries...

As your device will be displaying data from OpenWeatherMap you need an "API key" from them.

1. Go to https://openweathermap.org/price

2. note of the features in the "Free" column.

3. By using the free plan you are limited to 60 calls per minute.

4. In the "Free" column click on "Get API key and Start".

5. Once the API key is created you can come back to this page any time to edit or delete it.

API key which will be required in our code in the next step.

Start the Arduino IDE

File > Open

find and select esp8266-weather-station-color.ino from the previous step.

Configuration & customization

In one of the tabs the IDE opened settings.h. Go through the file and adjust the two handful of configuration parameters.

They are all documented inside the file directly. Everything should be self-explanatory. Most importantly you will need to set the OpenWeatherMap API key you obtained in a previous step

In the source code you will find a file named settings.h. Some changes in this file are required for customisation:

WiFi:

#define WIFI_SSID "yourssid"

#define WIFI_PASS "yourpassw0rd"

API key for OpenWeatherMap:

Enter your API key in line 38 of settings.h

String OPEN_WEATHER_MAP_APP_ID = "your_api_key";

Your location:

Go to https://openweathermap.org/find?q= and search for a location. Go through the result set and select the entry closest to the actual location you want to display data for.

It'll be a URL like https://openweathermap.org/city/2246575 The number at the end is what you assign to the constant below.

Enter the number and name of your location in line 45 and 46 of settings.h String OPEN_WEATHER_MAP_LOCATION_ID = "2246575"; String DISPLAYED_CITY_NAME = "Chapra";

Time:

Please choose your timezone in line 65 of settings.h
#define GMT+5:30

Upload code to device.
last step is to upload the code upload the code, just hit the upload arrow button. -:)

It works great

For a quick test, just powering with powerbank The weather station should be turned ON.

The touch has only one function. You can choose the displayed time format by touching in the upper part of the screen.
