<p>In this project,we leverage the power of the Internet of Things (IoT) to create a sunrise alarm. The device automatically identifies your geographical location,allowing you to customize the alarm accordingly.</p>



<p>To bring this <a href="https://eduengteam.com/2022/12/iot-development-prototypings-for-2022.html" class="ek-link">IoT project</a> to life,we'll utilize the ESP8266 microcontroller board and integrate it with the Weather API. Before getting started,ensure you've registered an account on www.weatherapi.com to obtain the necessary API key for building this innovative device.</p>



<p></p>



<h2 class="wp-block-heading">Essential Components<br>To prototype this device,you'll need the following components:</h2>



<ol>
<li>ESP8266 x1</li>



<li>Buzzer x1</li>



<li>Push button x1</li>



<li>Resistor 330Ω x2</li>



<li>LED x1</li>



<li>Breadboard</li>



<li>Connecting wires/Dupont wires</li>
</ol>



<h2 class="wp-block-heading"><strong>Circuit connections</strong></h2>



<p>To assemble this device,you'll require an ESP8266 microcontroller board. Follow these steps:</p>



<ol>
<li>Connect the push button to pin GPIO4. Attach one terminal of the push button to the ESP8266's 3V pin using a 330Ω resistor. Also,connect this terminal to GPIO4. Connect the other push button terminal to the ground.</li>



<li>Interface a buzzer with GPIO5 on the ESP8266. Connect one terminal of the buzzer to GPIO5 and the other terminal to the ground.</li>



<li>Connect an LED to GPIO10 on the ESP8266,incorporating a 330Ω series resistor.</li>
</ol>

<h2 class="wp-block-heading">Creating an Account and Obtaining API Key for Weather Integration</h2>



<p>To operate this device,it relies on the Weather API. Register for an account on www.weatherapi.com (click the 'Sign up' button on its homepage) and obtain an API key.</p>



<figure class="wp-block-image aligncenter"><a href="https://www.engineersgarage.com/wp-content/uploads/2023/11/P45-02-WeatherAPI-Website.png"><img src="https://b2600043.smushcdn.com/2600043/wp-content/uploads/2023/11/P45-02-WeatherAPI-Website.png?lossy=0&amp;strip=1&amp;webp=1" alt="" class="wp-image-79911"/></a></figure>



<p>Fill in your details to complete the sign-up process.</p>



<figure class="wp-block-image aligncenter"><a href="https://www.engineersgarage.com/wp-content/uploads/2023/11/P45-03-WeatherAPI-Signup.png"><img src="https://b2600043.smushcdn.com/2600043/wp-content/uploads/2023/11/P45-03-WeatherAPI-Signup.png?lossy=0&amp;strip=1&amp;webp=1" alt="" class="wp-image-79912"/></a></figure>



<p></p>



<p>Check your registered email account for a confirmation email. Open your email and confirm your Weather API sign-up.</p>



<figure class="wp-block-image aligncenter"><a href="https://www.engineersgarage.com/wp-content/uploads/2023/11/P45-04-WeatherAPI-Account-Verification.png"><img src="https://b2600043.smushcdn.com/2600043/wp-content/uploads/2023/11/P45-04-WeatherAPI-Account-Verification.png?lossy=0&amp;strip=1&amp;webp=1" alt="" class="wp-image-79913"/></a></figure>



<p>Then,login at www.weatherapi.com with your registered credentials.</p>



<figure class="wp-block-image aligncenter"><a href="https://www.engineersgarage.com/wp-content/uploads/2023/11/P45-05-Weather-API-Login.png"><img src="https://b2600043.smushcdn.com/2600043/wp-content/uploads/2023/11/P45-05-Weather-API-Login.png?lossy=0&amp;strip=1&amp;webp=1" alt="" class="wp-image-79914"/></a></figure>
