This is a small display that shows the current electricity consumption, together with a graph of the today"s electricity price, using either NordPool or Tibber. The software pulls the data from a Home Assistant instance, so all sources must be available there.

STL files are available for 3D printing a casing for the display. Two variants - one straight for putting on a wall, and one tilted, optimal for a desktop display.

If you want to make it your self then Let’s start the tutorial, So you can make it in an easy way with an ESP8266, TFT display, and other few components.

Arduino nano RP2040 has fast SPI so it can work to run a uncanny eye on TFT display. you can use this board and adafruit libraries to connect this board, visitadafruit pagefor more details but for now we are using wemos D1 mini board.

Wemos D1 mini is an ESP8266 breakout board. It has CH340 ic to easily communicate with ESP8266 over serial, also this CH340 is helping to program the ESP8266 over serial, But first, you have to install the driver for the CH340 chip if you don’t know how to install the CH340 driver then read firstbegin with Wemos D1 mini.

TFT stands for thin-film-transistor liquid-crystal display. It is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast.

Before we upload the program to the Wemos D1 mini-board, we have to install the driver first. The Wemos D1 mini board has a CH340 chip to communicate and program ESP8266 on board. But you are not able to communicate via CH340 without installing the driver.

To make this article, short and sweet I am not gonna explain the driver installation process, but I explained it in my old articlebegin with Wemos D1 mini,Go and check out my article to install the CH340 driver.

If your driver is successfully installed then you are ready to program the Wemos D1 mini-board, But before uploading the Code firstly install the “TFT_eSPI” library.

OpenArduino IDEand go to theSketch >> Include Library >> Manage Librariesand here type “TFT_eSPI” and hit enter. Now scroll down you will see the library, install the latest version of the library.

When your library is successfully installed connect your Wemos board with your PC and download the folder from myGitHubpage and open it. You will find theEye pendantcode in the folder, open the code and select the correct board and correct port.

Now you will see an Uncanny Eye on your TFT screen as shown in the image, if your screen is still blank then check the connection, if still your screen is blank try to connect it with Arduino Uno but remember to connect 1k resister on each pin because Arduino Uno works on 5V logic but TFT works on 3V3 logic.

Now TFT with Wemos D1 mini board is working fine but it is working with the USB supply via Computer or laptop. We need to make it more portable so we can easily carry it and take it where we want.

If you have noticed there is a 330ohm resistor connected on the D2 pin, this is because the 134N4p module requires a minimum of 60mA current draw to wake up continuously, it currently does not reach 60mA it will restart. So I connected this resistor on this D2 pin and it will be high when code is running on the Wemos board. The total current of Wemos board and TFT is 50mA so I connected this 330 resistor and because the pin can give 3.3v output the current draw across the resistor is 10mA, the overall current is 60mA so 134N3P module will not shut down in the middle of it still getting restart just decrease the resistance value.

Take your 3D print, but make sure it is fully dry. First of all, put TFT inside the front section of the 3D print which has a hole. Put some hot glue to make it stable in place.

I inserted the battery just behind the TFT display and the Wemos module behind the 134N3P module, you will see some different setups in the image, what was wrong I have changed it later but forgot to take pictures.

In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

In which “Hello, World!” is the text you want to display and the (x, y) coordinate is the location where you want to start display text on the screen.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.

If you want to make it your self then Let’s start the tutorial, So you can make it in an easy way with an ESP8266, TFT display, and other few components.

For most of my Arduino & ESPHome projects I use a Wemos D1 mini (v3.1.0) or Wemos D1 mini Pro (v1.1.0). The third board of the family is the is the D1 mini light. I never used one of the light versions, most of the time you can get the D1 mini & D1 mini pro for almost identical prices at alipexpress.com.

I also like the board because it is little smaller than a classic Node MCU board. The dimensions are 34.2 mm x 25.6mm. It is so small; it even fits into a small dollhouse Mini TV.

Wemos recently upgraded both boards. The Wemos D1 mini is now on version 4.0.0 and the Wemos D1 mini Pro on v2.0.0. Both boards got USB type C connectors instead of micro USB. The pro version also got a lithium battery interface charging interface and a LOLIN I2C Port. To fit everything on the board D1 mini Pro has grown a bit.

The pinouts of the D1 mini vs. D1 mini Pro are identical, also the D1 mini shares the same pin layout. And with with the latest board versions of the D1 mini (v4.0.0) vs. D1 mini Pro (v2.0.0) Wemos keeps the pin layout compatible.

There are only minor differences between the D1 mini and the D1 mini Pro (V1.1.0) I have. For most projects it should not really matter which board you use. The pin out layout is the same.

The most obvious visible difference is the ceramic antenna and the external antenna connector on the board. With the ceramic antenna the D1 mini Pro should have better WiFi reception than his little brother.

Wemos provides a wide range of pre-build extension shields for the D1 minis. There is a wide range of LED, OLED, TFT and ePager display boards for interactive projects.

Various types of environmental sensors are available. You can choose from simple temperature & humidity sensors, air quality sensors or a standard PIR sensor. Next to the sensor shields Wemos also has a selection of motor driver shields for different areas of applications.

If you can"t find a suitable shield for your project, Wemos offers so-called base shields. These are empty prototyping boards for your DIY projects. They are available in different form factors (1x, 2x & 3x) and can also be used to stack other shields.

All shield boards typically come with male and female pins are already included in the package. A full list of official shields can be found on the Wemos Wiki.

ESPHome works on top of PlatformIO which has support for a wide range of ESP8266, ESP32 and various other development boards. Wemos D1 boars are supported as well, to use them in your ESPHome projects use:esphome:

I recommend to always use the Wemos specific board name instead of a generic esp board or board: nodemcuv2. While these might work as well the pin mapping might be mixed up and you will get unexpected behaviour.
