Once Arduino board is connected with USB, can flash new code: cd arduino_number_guessing_game && pio run -t upload. The USB connection can then be used to provide 5V power to the Arduino board and if ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

[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… ...

At the time of this writing, a number of Arduino boards exist: Arduino UNO, Nano, Mega, Mini, Pro and others (see Resources for a complete list). The Arduino UNO (Figure 1) is the latest version of ...

It would be fun to test however, and I think it wouldn’t be too hard to hit at least 115,200 bits per second coming in over serial and being pushed out over the parallel port with the current setup.

The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc.

This project uses a webcam to count the number of fingers held up (from 1 to 10) and displays the result on a physical 7-segment display connected to an Arduino Uno. Real-time hand and finger ...

BTW – More for just looking at, as it has got all sorts of hidden odd characters added by WordPress and the ‘wrong’ spaces, so it will not run if you just copy and paste without first cleaning it up.

This is all part of my personal challenge to quickly and accurately manually set 16bit numbers for microcontrollers. Thanks to the earlier hard work of others, writing libraries and how-tos, it worked ...
