When we use the USB cable to listen or talk to our Arduino’s and microcontrollers we are using asynchronous serial. MOST of the time we leave out the asynchronous part of the label. There are synchronous versions of serial as well — we will address those elsewhere.
The following posts explore different aspects of asynchronous ( basic ) serial communication.

Serial Demo – 2024
In this tutorial we will look at a quick demonstration of a serial bridge between an esp32 and a p5js sketch. Because web browsers are sandboxed and do not generally permit direct serial messages (this is changing in 2024 --but...

Simple Serial with oLed Screens
One difficult challenge in working with serial is being able to debug (or see) the data that arrives at a microcontroller via serial. Serial connects are simple and powerful --but on the microcontroller side they can be VERY hard to...
