The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc. It was first developed back in 2003 as an affordable ...

You can use the XL320-Setup sketch included in the examples to configure the buad rate (9,600 / 57,600 / 115,200), set the servo ID number (0 ... The XL320-Setup sketch uses the hardware serial port ...

[Andrew] wonders why the SerialUSB() function on the Cortex M3-based Arduino Due is so much faster than Serial() on the Uno or Nano, and shares his observations in this short video. He sets up an e… ...

It also lets you send strings – e.g. commands or data – from the computer to the Arduino board. The Serial Monitor can be handy for debugging by letting the sketch send text messages about what it is ...

I like to visualize things, so I decided to prepare this simple tutorial to help you better understand how to visualize data using Arduino. This tutorial assumes that you have some basic electronics ...
