IOT WALLET

If you've invested money in crypto coins, you probably already know that they are extremely unpredictable. They can change overnight and you never know how much 'real' money you still have in your wallet. The same is true for stock markets. You put a little faith in a particular stock and, out of nowhere, the market thinks it's worthless the next day. So how do you track these assets and know their current value? You can work with some spreadsheets and update them regularly. Or you can create your own gadget to check these values for you: an IoT wallet! For this project, I worked on a Google spreadsheet to track my assets and update their values for a particular currency, based on the ticker values retrieved from the Internet. This spreadsheet is accessible from an ESP32 using Wi-Fi connection, and a summary is shown on an OLED display. A 3D printer was used to create a wallet, in which I embedded some electronic components to create my first IoT wallet prototype. Did you know that you can buy a Creality 3D CR10 for only $359.99?
