Hello friends, I hope you all are doing great. Today, I am going to share the Arduino UNO R4 WiFi Library for Proteus . The UNO R4 WiFi is the newest member of the UNO family: the same size, shape and headers as the classic UNO, but with a 32-bit Renesas RA4M1 , an ESP32-S3 module for Wi-Fi and, right on the board, a 12 x 8 red LED matrix . With this library it runs your UNO R4 WiFi sketch in Proteus - WiFiS3, Arduino_LED_Matrix, the D0 to D13 and A0 to A5 pins, Serial on the USB - and shows every frame on the board's matrix.
