The "serial_to_DAC_to_speaker" directory contains the Arduino code. The "serial_sender" directory contains a rather trivial C program (to run on the computer) that copies a file to a serial port.

The Arduino ecosystem is an amazing learning tool, but even those of us who love it admit that even the simplified C Arduino ...

A library to communicate messages from Unity to Arduino. The communication is done over serial port with an Arduino connected with USB to the computer running the Unity app. The library contains a ...

One of the strong points of Arduino is its easy-to-use serial port which makes it simple to export data, to send commands to it, or to help with debugging. A Serial Monitor and a Serial Plotter are ...

You haven't directly made use of the serial communication between the host computer and the Arduino board. First, I'll describe how to write a basic client/server style program.

You can read the state of a button using Arduino and a few lines of code. The actual state is shown in the Serial Monitor window as 0 or 1, 0 meaning the ...

The Serial Plotter built into the Arduino IDE creates graphs from numerical data. Unfortunately, there is no user manual for it.
