In this project, we will use an ESP8266 to create a weather forecaster. It's the worst feeling in the world to be caught outside on a wet day without an umbrella, and I think most people feel the same way. When we are in a hurry, we frequently fail to pay attention to the weather widget that is displayed on our smartphones, even though it provides a forecast of the upcoming weather.

Therefore, it would be convenient to have a device that hangs on the back of the door and serves as a constant reminder to take an umbrella with you whenever you leave the house on a day that there is a chance that it will rain. The weather forecast is displayed on this device in the form of a change in the color of the LED. This piece of technology wouldn't have an alarm or a screen; instead, it would just have a few LEDs that were designed to blend in with their surroundings.

The following is an exhaustive list of the components that you will require for this project (click the links below to locate the items at

ESP8266 12-E, more information can be found at Best ESP8266 Wi- Fi Development Boards. 4x LEDs (different colors to represent different weather conditions) 4 resistors in total (220 or 330 ohms should do the trick) Breadboard A set of jumper wires

Open Weather Map Because the Open Weather Map API is the foundation of this project, it is necessary to register on their platform and acquire an API key before we can begin the process of putting together the schematics and writing the code for this project. The free plan offered by OpenWeatherMap gives you access to all of the features you require for this demonstration. You will need an API key, also known as the APIID, in order to use the API. To get an APIID: Launch your web browser, and navigate to the OpenWeatherMap website. Click the button labeled " Sign up" to set up your free account. After you've successfully created an account, you'll be taken to a dashboard that features a number of different tabs. Go to the tab labeled API Keys , and copy your individual Key. You will need this one-of-a-kind key in order to retrieve information from the website. Make a copy of this key and save it to your computer; you'll need it in a little while.

Enter the following URL into your browser's address bar, making sure to replace the information in the sections denoted by curly brackets with the appropriate details for the location you've selected as well as your own

Replace "your city" with the city whose data you require, "your country code" with the country code corresponding to that city, and "your API key" with the one-of-a-kind API key we discovered for you earlier. For instance, our Application Programming Interface (API) URL for the city of Porto in

Please take note that additional information regarding the use of the API to get weather information can be found here. If you paste your URL into your browser, it should give you a bunch of information that is relevant to the weather forecast for where you are. Be sure to guard your one-of-a-kind API key, and we will then proceed to the section on the code.

The following figure provides an explanation of what each LED represents: Rain on Day 2, a clear sky on Day 3, snow on Day 4, hail on Day 5, and hail

These days, the purpose of computing is to develop a natural user interface that will allow people to communicate with their computers. We are looking to technologies such as AR (Augmented Reality) to help make this a reality, but the fact of the matter is that we are all growing tired of having to constantly look at our phones and computers for even the smallest piece of information. I believe that it would be extremely helpful to have this project hung up around the house in a location where it would be easy to check the weather before leaving the house. In order to take this project one step further, I might incorporate a battery backup into a 3D-printed enclosure and give it a more streamlined appearance. When that is complete, you can count on me to let you know about it.
