Apart from understanding the Arduino's code language ... In addition to this main processor, the Nano also has another chip on board, the FTDI FT232RL, which handles USB communication as the ...

For those worrying that [Faransky] is relying on the PWM functionality of the Arduino Nano to generate waveforms ... as a voltage divider on the chip’s output. To wrap up the build, he added ...

This build relies on a solid-looking lead screw to move a carriage up or down. An Arduino Nano acts as the brains, a stepper motor drives the lead screw, and a small display shows stats such as ...

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.
