When I saw what he could do a ESP8266, I wanted to build a small weather station.This is the evolution of my <a href="https://create.arduino.cc/projecthub/Tittiamo/weather-clock-c7e040?ref=user&ref_id=79531&offset=1">weather clock.</a><h3 >Set the ESP8266-01</h3><div id="gallery"><img id="gallery" src=https://projects.arduinocontent.cc/ee2661f8-872b-4c57-b701-b51180917496.jpg /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/fdcefda7-7916-47db-bbc0-1af09e8b09a4.jpg /><figcaption> </figcaption></div><h3 >Connect the ESP</h3>Connect the ESP to Arduino following the pattern in the figure, be sure to fuel the ESP with a voltage of 3.3 volts using a voltage regulator (I used an LM317) powered by an external source, because needs a lot of energy that Arduino can not give.<h3 >Upload to Arduino</h3>Upload to Arduino / Genuino the code: <a href="https://create.arduino.cc/editor/Tittiamo/7e4b0e1b-ffd9-4ab7-b007-8c24c063c152/preview">https://create.arduino.cc/editor/Tittiamo/7e4b0e1b-ffd9-4ab7-b007-8c24c063c152/preview,</a> open the serial monitor and give the command &#34;AT&#34; followed by ENTER, if nothing appears you need to set the speed of the serial monitor, make several attempts until you see &#34;OK&#34;.<h3 >Search WiFi</h3>Now type the command &#34;AT+CWMODE=1&#34; to set the ESP as &#34;Client&#34;. Give the command &#34;AT+CWLAP&#34; to see which WiFi networks are nearby, with the command &#34;AT+CWJAP=&#34;SSID&#34;,&#34;password&#34; &#34; you connect the ESP to your WiFi network. To check if it is well connected, type &#34;AT+CIFSR&#34;. Now that the ESP8266 has been set, you can switch to connect other components.<h3 >Prototyping</h3><div id="gallery"><img id="gallery" src=https://projects.arduinocontent.cc/7b0907b9-aedc-4cf9-8ba1-ff1872d07129.jpg /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/260623e8-3d6b-4d5d-acd3-71ae633cbeab.jpg /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/d02b7201-4774-4da7-a0df-56e29a53c699.JPG /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/6c07f691-5d96-46a4-82b9-6e408ccf7073.JPG /><figcaption> </figcaption></div><h3 >More Connections</h3>Connect the rest of the components following the <a href="http://fritzing.org/projects/weather-station-thingspeak">Fritzing </a>scheme.Record a &#34;thingspeak&#34; <a href="https://thingspeak.com/">account</a> and create a new channel, give it a name and description.<ul ><li >Field 1: Temperature</li></ul><ul ><li >Field 2: Humidity</li></ul><ul ><li >Field 3: Pressure</li></ul><h3 >API Key</h3>Save and open the API Keys tab, and store the &#34;api_key reading&#34;.Load the <a href="https://create.arduino.cc/editor/Tittiamo/37999913-81ae-4a32-a79d-cc68b18c5c72/preview">code</a> in Arduino, replace the line 35 with your api_key, in line 26, replace the altitude with that of your location, load the design, and enjoy the card's results: &#34;Private View&#34; into Thingspeak.If you want to publish your channel, go to settings and give the flag to &#34;make public&#34;.<h3 >Arduino Code</h3>Libraries: <a href="https://github.com/adafruit/DHT-sensor-library">DHT,</a> <a href="https://learn.sparkfun.com/tutorials/bmp180-barometric-pressure-sensor-hookup-/installing-the-arduino-library">SFE_BMP180</a> <h3 >Assembling</h3><div id="gallery"><img id="gallery" src=https://projects.arduinocontent.cc/b5214481-f379-4d26-b6aa-2eda5f3350e6.JPG /><figcaption>Arduino Standalone</figcaption><img id="gallery" src=https://projects.arduinocontent.cc/0089e3ce-6008-4482-b9d5-c1ac12dc5dca.JPG /><figcaption>P.C.B. for BMP180, DHT22, ESP8266</figcaption><img id="gallery" src=https://projects.arduinocontent.cc/84fc6a67-02ee-40c7-95db-5e8350de01de.jpg /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/13c681c7-f10a-4037-bcfd-fea8d4cbd75c.jpg /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/bc4e9098-7765-44f5-8f0f-cb0291d7af6c.JPG /><figcaption>foreground Arduino standalone</figcaption><img id="gallery" src=https://projects.arduinocontent.cc/fda75f71-d17b-426d-8939-52259bf4d24b.JPG /><figcaption>foreground P.C.B.</figcaption><img id="gallery" src=https://projects.arduinocontent.cc/8eba2b26-8e52-4b41-ba15-cef5aec0f4e1.JPG /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/5ed588f3-9cf6-45f6-afaa-12f0468e759c.JPG /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/418b23bf-d27c-43e0-8862-eba354261748.JPG /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/568a9b81-58b2-4efd-bf72-d27b7bd51e1f.JPG /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/b93e609b-2778-41b7-938e-c9b6e3dfb0ad.JPG /><figcaption> </figcaption></div><h3 >Testing</h3>Tested everything worked, I built the circuit on a breadboard thousand holes.
