 This repository contains a program to create a **freely paintable canvas** with an **Arduino UNO R4 WiFi** and a **3.5" ILI9486 touch screen display shield**. The contents of the canvas can be **saved to and loaded from a server** running on your **PC/cloud VM**. Connections to WiFi can be made on the fly using a **full android-style keyboard**.
 
-Overall, the project attempts to provide a smartphone-like experience using just the Arduino UNO R4 WiFi and Display Shield, both of which are relatively inexpensive and easy to acquire. Pictures of the App are included the following sections.
