<h3 >About the project</h3><blockquote >Problem :</blockquote>We don't have a lot of options for smart soda machines. They usually don't work with smart homes. The ones we can buy are way too expensive and hard to maintain.<blockquote >Soulution :</blockquote>That's why i came up with an cheap DIY alternative. It works With Alexa. In this page you will find all the instructions to make it. <blockquote >Result :</blockquote>At the end you will have an amazing low cost soda machine that you will be able to connect to any smart home device by triggering routines. In Alexa app you can also set times to triger them. Soo you can set it to make you sodas at every morning! It will make your life way easier! You will be able to control it from anywere, because it's connected to arduino cloud.Also you will learn new things/skills about IoT and Arduino! This will be a lot of fun!<h3 >My YouTube video</h3><div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe frameborder="0" allowfullscreen="" src="https://www.youtube.com/embed/wFm2wV3nNAo" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" style="width: 100%; height: 100%;" data-index="0" data-file-size="0" data-origin="100%,56.25%"></iframe></figure></div><h3 >If you are an complete beginner</h3>Here's some resources for beginners :<a href="https://www.makerspaces.com/how-to-solder/">How to solder</a><a href="https://www.arduino.cc/en/Guide/Introduction">What is Arduino</a><a href="https://hackr.io/blog/arduino-projects">Easy Arduino projects</a><a href="https://www.dummies.com/article/technology/computers/hardware/arduino/how-to-upload-a-sketch-to-an-arduino-164738/">How to upload to Arduino</a> <figure><img src=https://projects.arduinocontent.cc/aa1ce7cc-f7fd-455d-9e49-7871233e6e36.jpg /><figcaption> </figcaption></figure><h3 >The frame</h3>At first, make a frame.
