Meanwhile, the Arduino Mega is getting the same USB chip along with an ATMega2560 processor with twice the memory. Right now only 128K is available, but that's a software limitation and they're ...

It’s a significant update. The Arduino UNO and Arduino Mega 2560 update the Duemilanove and Mega respectively. They now use an ATMega8U2 instead of an FTDI USB to serial converter chip.

Apparently, so does [salmec] who developed the Mowerino around an Arduino Mega 2560 board. As you might expect, the robot uses sharp blades so, you probably want to be careful.

What next? World peace, maybe? Child rearing? To be precise, an Arduino Mega 2560 board controls six NEMA 17 stepper motors (one for each face of the cube) via a CNC shield with DRV8825 drivers.

Another advantage is the small footprint of the Narrow boards. They are approximately 1/5 the size of an Arduino Mega 2560 board, making them perfect for projects where space is a constraint.

The Arduino Cable Tracer has been created using an Arduino Mega 2560 board with its IO pins connected to USB-A, USB-C, Micro-B, and Mini-B ports.

In comparison, the Arduino Uno, Leonardo, and Mega 2560 boards all have theoretical ADC speeds of 15 ksps.... ( ( (And they're just getting warmed up!))) ...

How impressive is this? An Arduino-based system that automatically solves a Rubik's cube, usually within 1.5 to 2 seconds... It's impressive and fast. Visual processing, non-verbal reasoning, physical ...
