In this post I look at a few different techniques for sending complex data and commands; starting with functions that are built in the Arduino language and moving to our own functions that, IMHO, perform better and allow for better code. Read more Arduino Serial Part 3: Getting started with...
The Arduino UNO R4 WiFi is equipped with an Espressif ESP32-S3 chip from Lexin Technology, which not only provides Wi-Fi and Bluetooth connectivity, but also has a powerful microprocessor with a clock speed of up to 240MHz, 512kB of SRAM, and 384kB of ROM. In addition, it has an OFF...
