Have you ever dreamt of having a smart list that allows you to store all the groceries you need to buy to an SD card in seconds? This device aims to make all of that as easy as pressing a button, wherever the user is located, he/she can simply type something in Blynk's Terminal and the written data will be immediately stocked on an SD card at home. It's as simple as that. But the best part is that you can get this project set up in less than 30 minutes.
