The Arduino Nano interprets this data and outputs it over SPI to a DAC which outputs a signal which is then amplified and fed to the human brain courtesy of op-amps, boost converters and sponge ...

For those worrying that [Faransky] is relying on the PWM functionality of the Arduino Nano to generate waveforms ... an interface to control it over SPI. Unfortunately, the AD9833 doesn’t ...

However, Arduino also offers this board without headers ... You'll notice a difference between the SPI and I2C/TWI pins, as well. On the Nano, the SPI pins are on digital pins D10 to D13, and ...

The Arduino Nano and Raspberry Pi Pico have distinct pin ... On the Nano, you can access one UART (pins D0 and D1 as RX and TX), one SPI (pins D10 to D13 as SS, MOSI, MISO, and SCK), and one ...
