 ### Starter Kit R4 Online Projects
 
-The Starter Kit R4 includes a set of online projects. These projects build on the skills developed in the first 14 lessons, introducing topics such as computer interaction via USB (HID), capacitive touch and enhanced use of the LED matrix. The first online module, **"Welcome Online"**, provides an introduction to the Arduino Cloud platform and how to use it with your kit.

 The UNO R4 WiFi supports power inputs via USB-C or the VIN pin (DC barrel jack). A buck converter (ISL854102FRZ) regulates VIN input (6-24 V) down to 5 V. USB input is internally dropped to ~4.7 V due to a Schottky diode.
