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.

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 ...

For this project I am using the Arduino Mega 2560. Absolute Number of Steps Matter First, we should consider the number of steps needed for a full rotation of the motor shaft. In this prototype I used ...
