This is the VBA Serial Port function set adapted for use with Arduino devices. No other files, licences, payments or registrations are required. Functions can be used directly in Excel cells as ...

If you use the Arduino IDE to program the ESP32, you might be interested in [Andreas Spiess’] latest video (see below). In it, he shows an example of using all three ESP32 UARTs from an Ardui… ...

This enables web apps to be written that can communicate with your local serial device such as an Arduino, CNC controller, or any device that communicates over the serial port. Since version 1.82 you ...

Serial.print() can be slow, intrusive, and unreliable, depending on the baud rate, buffer size, and serial port availability. Fortunately, there are other ways to debug your Arduino code without ...

Introduction:In Arduino environment, it's convenient to access BT SPP like a serial port and react to the command string sent from the BT serial port. Many Arduino projects have utilized this way ...

In this paper, a serial port based debugging tool for the Arduino platform is presented. The tool is based on a modification of the Arduino IDE (Integrated Development Environment) and libraries. It ...
